| 20090085617 | RAMP VOLTAGE CIRCUIT - Implementations related to ramp voltage generating circuits and systems implementing the same are presented herein. | 04-02-2009 |
| 20090121642 | Organic Light Emitting Diode Driver - Pulse width modulation (PWM) of a drive current to an organic light emitting diode (OLED) is performed by a circuit subjected to corresponding signaling. | 05-14-2009 |
| 20090121778 | Anti-Shock Methods for Processing Capacitive Sensor Signals - A low impedance coupling to bias voltage dissipates abnormal charge levels within a microphone in response to a shock event such as dropping or bumping. High impedance coupling to bias voltage is thereafter restored. | 05-14-2009 |
| 20090140898 | Jitter Insensitive Single Bit Digital to Analog Converter - Systems and methods for a jitter insensitive 1-bit digital to analog converter (DAC) are described. The jitter insensitive 1-bit DAC employed in the feedback loop of a delta sigma analog to digital converter (ADC) converts a 1-bit digital data into the corresponding analog output. | 06-04-2009 |
| 20090140899 | Double Sampling DAC and Integrator - This disclosure relates to systems and methods for analog to digital conversion using delta sigma modulation. To this end, the delta sigma modulator includes a double sampling DAC and integrator and a 1-bit comparator, with reference loading insensitivity. | 06-04-2009 |
| 20100097255 | Temperature Compensated Delta-Sigma Modulators with Logarithmic Dynamic Range - Disclosed herein is a delta sigma (ΔΣ or DS) modulator and method for operating the same, the modulator including at least a first proportional to absolute temperature (PTAT) element that conditions an input signal, and a second PTAT element that conditions a reference signal. | 04-22-2010 |
| 20100308915 | Phase Margin Modification In Operational Transconductance Amplifiers - The present disclosure relates to phase margin modification in operational transconductance amplifiers. | 12-09-2010 |
| 20110037629 | Coupled Delta-Sigma Modulators - An apparatus and method for reducing error in converting a multi-bit signal to a single bit signal. An analog delta-sigma modulator receives an analog signal and converts it to a multi-bit digital signal that is provided to a digital delta-sigma modulator. The digital delta-sigma modulator introduces error by converting the multi-bit signal to a single-bit signal. The error from the conversion is fed back to the analog delta-sigma modulator which incorporates the error information into the analog signal before it is converted to a multi-bit digital signal. | 02-17-2011 |
