Abstract

An ADC system includes a sigma-delta modulator that receives an analog input and provides a first digital output and an analog output. An ADC, coupled to the sigma-delta modulator, receives the analog output as an input and provides a second digital output. A digital processor, coupled to the sigma-delta modulator and the ADC, receives the first and second digital outputs and provides a digital representation of the analog input.
