Abstract
An input stage circuit for a sigma-delta analog-to-digital converter circuit receives a digital-to-analog converter generated feedback signal and an analog current input signal to generate a difference signal applied to an integrator circuit. A single bit quantization circuit quantizes an output of the integrator circuit to generate a bit signal that is applied to an input of the digital-to-analog converter. The input stage circuit includes a switched input capacitor controlled by first and second, non-overlapping, clock signals.
