Abstract: A digital calibration system for an analog-to-digital converter system includes a computational system receiving digital bits from an analog-to-digital converter representing selection of elements of the digital-to-analog converter in response to an analog input. The computational engine produces a digital output representative of the analog input during conversion operation, and digital values for adjustment of an adjustable analog source during calibration. Further, a digital system comprises a radix-less-than-two non-configurable digital-to-analog converter, a comparator system connected to the converter, and a computational system configured for SAR calibration and conversion.

Abstract: A multistage comparator is calibrated to remove quasi-autozero voltages derived from the native comparator offset and autozero switch charge injection offsets. A multistage comparator includes a plurality of series connected amplifiers each having a programmable source, and further including a latch. A calibration method for a multistage comparator includes calibrating the first of a series of amplifiers first for both voltage offset and charge injection errors thereby to remove the quasi-autozero voltage and charge injection offsets.

Abstract: An auto-calibrating companion bit successive approximation system uses sampling and balancing capacitors in a charge redistribution digital-to-analog converter having multi-valued capacitors of magnitudes enabling redundant expression of electric charge values. Companion bits are used with sets of balancing capacitors for successive approximation of sampling voltages. A charge redistribution digital-to-analog converter has a sampling and balancing capacitors including associated companion bit capacitors represented by digital weights which are saved in memory. A non-binary weighted set of capacitors provides redundancy in a charge redistribution digital-to-analog converter employed in a successive approximation register architecture.
