20140091957 | DYNAMIC DITHERING METHOD AND APPARATUS FOR ANALOG-TO-DIGITAL CONVERTERS - A dynamic dithering method is provided for improving linearity in analog-to-digital converters. | 04-03-2014 |
20140055295 | METHODS AND APPARATUS FOR CALIBRATING STAGES IN PIPELINE ANALOG-TO-DIGITAL CONVERTERS - A calibration control circuit is provided for calibrating a stage in a pipeline analog-to-digital converter (ADC). The stage includes an analog-to-digital subconverter (ADSC) and a multiplying digital-to-analog converter (MDAC). The calibration control circuit includes circuitry coupled to comparators in the ADSC to force the comparators to output a predetermined digital output signal set by a calibration control signal when the ADC is in a calibration mode to thereby control reference switches in an analog multiplexer (AMUX) to selectively apply reference voltages to capacitors in the MDAC to obtain a predetermined stage residue signal. | 02-27-2014 |
20130207818 | METHODS AND APPARATUS FOR CALIBRATING PIPELINE ANALOG-TO-DIGITAL CONVERTERS HAVING MULTIPLE CHANNELS - Methods and apparatus are provided for calibrating stages in pipeline analog-to-digital converters (ADCs) having multiple channels. | 08-15-2013 |
