ABSTRACT:
An analog-to-digital converter system 10 is provided that comprises two separate banks of capacitors that are configured with a single operational amplifier 30 for each stage 29 within the system 10. The banks of capacitors are used in an interleaved fashion to simultaneously digitize analog input voltages and sample a reference voltage V.sub.REF to enable the digitization of a gain error associated with the operation of amplifier 30. This gain error can be combined with the raw digital output of the converter using an arithmetic logic unit 18 to result in a calibrated output for the system 10.
