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...	05/24/2012
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...	09/15/2011
