A switched-capacitor successive-approximation analog-to-digital (AD) converter is developed which incorporates a serial digital-to-analog (DA) subconverter for generating the threshold voltage sequence. Error analysis shows that a resolution higher than 12-b is attainable with the monolithic implementation using present CMOS technologies.
