Abstract :
A fourth order incremental analog to digital converter (ADC) is proposed which performs 16 bit conversions at a 50 kHz rate on sampled and held data. A new self-calibration scheme is presented which eases the matching requirements of capacitors, and the performance of the operational amplifiers in the ADC by changing coefficients in the digital postprocessing
