| 20080263482 | Method and Apparatus for Small Die Low Power System-on-Chip Design with Intelligent Power Supply Chip - A method and system of system-on-chip design that provides the benefits of reduced design time, a smaller die size, lower power consumption, and reduced costs in chip design and production. The process seeks to remove the worst performance and worst power case scenarios from the design and application phases. This is accomplished by planning the power supply voltage in the design phase along with its tolerance with process corner and temperature combinations. The established plan is then applied with communications between power supply integrated circuits and load system-on-chip. | 10-23-2008 |
| 20080297381 | METHODS OF USING PREDICTIVE ANALOG TO DIGITAL CONVERTERS - Methods and devices are disclosed for performing analog to digital signal conversion in shorter time and/or with less power consumption than that of a comparable analog to digital conversion that uses a conventional sequential approximation method based on a binary search. In one embodiment, a predictive guess is supplied as a digital first signal. The digital first signal is converted (D/A) to a counterpart, analog guess signal. A comparison is made between the analog guess signal and a received, analog input sample signal. The result of the comparison is used to improve on the initially supplied guess in a next cycle. Fewer cycles and less power is consumed if the initial guess is within a certain range of the actual magnitude of the analog input sample signal. In one embodiment, a digital modeler is used to model a process underlying the analog input sample signal and to thereby provide fairly good guesses. | 12-04-2008 |
| 20100111241 | Digital Phase Lock Loop with Multi-Phase Master Clock - A digital phase lock loop circuit with reduced jitter at the output is disclosed. The digital phase lock loop circuit includes a phase frequency detector that determines a phase difference between a feedback signal and a reference frequency signal to generate an error signal indicative of the phase difference. A numerically controlled oscillator generates a first oscillator output signal with a frequency proportional to the error signal and a second oscillator output signal indicative of jitter of the first oscillator output signal in reference to the reference frequency signal. A phase accuracy extender determines a delay amount from the second oscillator output signal and delays the first oscillator output signal by the delay amount to generate a phase-enhanced output signal with edges aligned with one of a plurality of reference clock signals. | 05-06-2010 |

| 20110062872 | Adaptive Switch Mode LED Driver - An adaptive switch mode LED driver provides an intelligent approach to driving multiple strings of LEDs. The LED driver determines an optimal current level for each LED channel from a limited set of allowed currents. The LDO driver then determines a PWM duty cycle for driving the LEDs in each LED channel to provide precise brightness control over the LED channels. Beneficially, the LED driver minimizes the power dissipation in the LDO circuits driving each LED string, while also ensuring that the currents in each LED string are maintained within a limited range. A sample and hold LDO allows PWM control over extreme duty cycles with very fast dynamic response. Furthermore, fault protection circuitry ensures fault-free startup and operation of the LED driver. | 03-17-2011 |
| 20110096572 | LOW POWER CONSUMPTION START-UP CIRCUIT WITH DYNAMIC SWITCHING - A start-up circuit in a switch-mode power converter that employs a Zener diode to provide a reference voltage to reduce the power consumption and the size of the start-up circuit. The start-up circuit also includes a coarse current source and a coarse reference voltage signal generator for producing current and reference voltage for initial startup operation of a bandgap circuit. The reference signal and current from coarse current source and the reference voltage signal generator are subject to large process, voltage and temperature (PVT) variations or susceptible to noise from the power supply, and hence, these signals are used temporarily during start-up and replaced with signals from higher performance components. After bandgap circuit becomes operational, the start-up receives voltage reference signal from the bandgap circuit to more accurately detect undervoltage lockout conditions. | 04-28-2011 |
