20100064674 | Energy Storage Bridge - The invention is an Energy Storage Bridge (ESB) consisting of air-tight steel pipes, which are used to store the compressed air as stored energy, also used as the load carrying structural elements of the bridge. The stored energy can be the unwanted grid power or the intermittent regenerated energy sources. When the energy is needed, the compressed air is released to convert back to electricity, or to make use of the compressed air to produce hot water during its compression cycle, and cool air at its decompression and expansion cycle when it absorbs heat- an air conditioning technology called Air Cycle Air Conditioning (ACAC) widely used in commercial aircraft. For sea-crossing bridges, because of their great lengths the bridge body volume is enormous, and because of their remoteness from populated areas, they suit well for mass energy storage attached to power plants. With safety measures built in the steel pipes, the ESB can be applied to city road bridges. Since these bridges are not far from populated areas, they can be used as small energy storage units that provide the nearby industrial and commercial complex as well as residential buildings hot water and compressed air for air-conditioning using ACAC technology. The process eliminates the conversion of compressed air back to electricity, but directly uses the compression and decompression cycles to supply hot water and cool air for air-conditioning to the nearby consumers. | 03-18-2010 |

20110221938 | Optical Black-Level Cancellation for Optical Sensors Using Open-Loop Sample Calibration Amplifier - A Optical Black Pixel (OBP) cancellation circuit corrects offsets in sensors in a CCD/CMOS image sensor when reading dark pixels such at the periphery. A pixel voltage is switched to a sampling capacitor during two phases of the same pixel pulse. Sampling capacitors and feedback capacitors connect to differential inputs of an amplifier. An accumulating capacitor accumulates voltage differences and generates a common-mode voltage that is fed back to another sampling capacitor that stores an amplifier offset. The sampling capacitor and accumulating capacitor and their associated switches form a discrete-time first-order low-pass filter that filters the pixel voltage during the first phase. In the second phase the amplifier acts as a unity-gain amplifier to output an average of the pixel voltage differences generated during an OBP time when blackened or covered pixels are read from the image sensor. | 09-15-2011 |
20120126736 | Bootstrapped High-Side Driver Control Without Static DC Current for Driving a Motor Bridge Circuit - A motor driver circuit for driving the gate node of a high-side driver transistor to a boosted voltage from a charge pump draws little or no static current from the charge pump. The gate node is pulled to the boosted voltage by a p-channel pullup-control transistor that is driven by p-channel transistors that are pumped by capacitors that cut off current flow to ground from the charge pump. An n-channel output-shorting transistor shorts the gate node to the output when the high-side driver is turned off. A coupling capacitor initializes the shorting transistor for each output transition. A p-channel output-sensing transistor generates a feedback to a second stage that drives the coupling capacitor. P-channel diode transistors and an n-channel equalizing transistor control the voltage on the coupling capacitor. | 05-24-2012 |

20100064674 | Energy Storage Bridge - The invention is an Energy Storage Bridge (ESB) consisting of air-tight steel pipes, which are used to store the compressed air as stored energy, also used as the load carrying structural elements of the bridge. The stored energy can be the unwanted grid power or the intermittent regenerated energy sources. When the energy is needed, the compressed air is released to convert back to electricity, or to make use of the compressed air to produce hot water during its compression cycle, and cool air at its decompression and expansion cycle when it absorbs heat- an air conditioning technology called Air Cycle Air Conditioning (ACAC) widely used in commercial aircraft. For sea-crossing bridges, because of their great lengths the bridge body volume is enormous, and because of their remoteness from populated areas, they suit well for mass energy storage attached to power plants. With safety measures built in the steel pipes, the ESB can be applied to city road bridges. Since these bridges are not far from populated areas, they can be used as small energy storage units that provide the nearby industrial and commercial complex as well as residential buildings hot water and compressed air for air-conditioning using ACAC technology. The process eliminates the conversion of compressed air back to electricity, but directly uses the compression and decompression cycles to supply hot water and cool air for air-conditioning to the nearby consumers. | 03-18-2010 |

20090146749 | Low-Voltage Oscillator with Capacitor-Ratio Selectable Duty Cycle and Single-Input Sub-Threshold-Conducting Comparators to S-R Latch - An oscillator operates at a very low voltage yet has a duty cycle that is set by a ratio of capacitors that are charged and discharged. Sub-threshold p-channel transistors conduct sub-threshold currents below the normal threshold voltage, and drive set and reset inputs of a set-reset S-R latch. The S-R latch drives the oscillator outputs. The oscillator outputs feed back to charging p-channel transistors that charge one plate of the capacitors. During half of the cycle, the charging p-channel transistor is off, allowing one plate of the capacitors to discharge through an n-channel discharge transistor. After a period of discharge determined by the capacitance of the capacitor, the gate of a sub-threshold p-channel transistor falls enough for sub-threshold current to flow, triggering the set or reset input of the S-R latch. Since sub-threshold currents are needed to toggle the S-R latch, the oscillator begins to oscillate below the threshold voltage. | 06-11-2009 |

20100164625 | Slew-Rate-Enhanced Error Amp with Adaptive Transconductance and Single Dominant Pole Shared by Main and Auxiliary Amps - An error amplifier can be used to control a power regulator transistor. The error amplifier has a main amplifier, a pull-up auxiliary amplifier, and a pull-down auxiliary amplifier that all drive an output. A compensating capacitor on the output sets a single dominant pole for all amplifiers, increasing stability. High slew rates are provided by increased slew current from the auxiliary amplifiers that turn on when the differential input has an absolute voltage difference larger than an intentional offset. The intentional offset is introduced into the auxiliary amplifiers by adjusting a p-channel to n-channel transistor ratio in a leg of the auxiliary amplifiers. A source degenerated resistor in the main amplifier reduces supply headroom and increases linearity by connecting sources of two differential transistors that receive the differential input. Cascode transistors increase gain and output impedance. Reliability is increased as no positive feedback is used in the amplifiers. | 07-01-2010 |
20100164761 | DUAL-USE COMPARATOR/OP AMP FOR USE AS BOTH A SUCCESSIVE-APPROXIMATION ADC AND DAC - A re-configurable circuit acts as an Analog-to-Digital Converter (ADC) and as a digital-to-analog converter (DAC). An array of binary-weighted capacitors stores an analog input. Switches connect different capacitors in the array to fixed voltages that cause charge-sharing with a terminal capacitor. The voltage of the terminal capacitor is compared by a re-configurable comparator stage for each different combination of the capacitors. The comparison results are analyzed to determine the closest digital value for the analog input. In DAC mode, the array capacitors are switched based on an input digital value. The switched capacitors connect to a charge-sharing line to generate an analog voltage that is applied to the re-configurable comparator stage. A differential amplifier generates a buffered analog voltage that is fed back to the other input of the re-configurable comparator stage for unity gain. The gain of the re-configurable comparator stage adjusts for ADC and DAC modes. | 07-01-2010 |
20100164770 | MULTI-STAGE COMPARATOR WITH OFFSET CANCELING CAPACITOR ACROSS SECONDARY DIFFERENTIAL INPUTS FOR HIGH-SPEED LOW-GAIN COMPARE AND HIGH-GAIN AUTO-ZEROING - An Analog-to-Digital Converter (ADC) has a Successive-Approximation-Register (SAR) driving a digital-to-analog converter (DAC) that generates an analog voltage compared to an input voltage by a series of stages. The last stage feeds a compare signal to the SAR. Each stage has a dual-input differential amplifier that operates as a unity gain op amp during an auto-zeroing phase and as a high-speed low-gain amplifier during an amplifying phase. The dual-input differential amplifier has two pairs of differential inputs. A secondary pair has an offset-storing capacitor across it, and connects to the output pair through feedback switches during auto-zeroing. A primary pair connects to stage inputs through input switches during the amplifying phase. Since two pairs of differential inputs are provided to the dual-input differential amplifier, the offset capacitor is completely isolated from the input pair. The current sink in the dual-input differential amplifier is adjusted higher during the amplifying period. | 07-01-2010 |
20110163799 | Bi-directional Trimming Methods and Circuits for a Precise Band-Gap Reference - A bandgap reference circuit has trimming-up resistors and trimming-down resistors for bi-directional trimming. PNP transistors have base and collectors grounded and emitters connected to parallel resistors. A difference resistor drives an inverting input of an op amp that drives a transistor that generates the bandgap reference voltage Vbg. A sensing resistor connects Vbg to a splitting node that connects to the non-inverting input through a first parallel resistor. The splitting node also connects through a second parallel resistor to the inverting input. Fuses or switches enable the trimming-up and trimming-down resistors. The trimming-up resistors are in series with the sensing resistor and the trimming-down resistors are in series with an output resistor that connects Vbg to reference voltage Vref. The circuit can be designed for a more typical process since bi-directional trimming allows Vref to be raised or lowered. Many circuits need no trimming when targeted for the typical process. | 07-07-2011 |

Each array has binary-weighted capacitors from a most-significant-bit (MSB) to a least-significant-bit (LSB), but the LSB capacitor is duplicated as a termination capacitor and a middle capacitor between upper and lower groups is also duplicated as a surrogate capacitor. During calibration, lower array capacitors are switched low while the upper capacitors are driven by a thermometer-code value on both X and Y arrays. The thermometer value is inverted to the X-array but remains uninverted on the Y array. The lower array bits are tested to final a calibration value that has X and Y side voltages balanced. | 03-28-2013 |
20130141264 | REDUCED RESIDUAL OFFSET SIGMA DELTA ANALOG-TO-DIGITAL CONVERTER (ADC) WITH CHOPPER TIMING AT END OF INTEGRATING PHASE BEFORE TRAILING EDGE - An analog-to-digital converter (ADC) has a chopper-stabilized sigma-delta modulator (SDM). The SDM uses switched-capacitor integrators to sample, hold, and integrate an analog input in response to non-overlapping multi-phase clocks. Chopper multipliers are inserted on the inputs and outputs of an op amp in a first stage integrator. The chopper multipliers swap or pass through differential inputs in response to non-overlapping chopper clocks. A master clock operating at a frequency of the multi-phase clocks is divided down to trigger generation of the chopper clocks. Delay lines ensure that the edges of the chopper clocks occur before the edges of the multi-phase clocks. The chopper multipliers have already switched and are thus stable when multi-phase clocks change so charge injection at switches controlled by the multi-phase clocks is not immediately modulated by chopper multipliers. This clock timing increases the time available to respond to charge injection at switches improving linearity. | 06-06-2013 |
