Abstract
A current mode sigma-delta modulator comprises an input node; a comparator that compares a voltage of the input node to a reference voltage and outputs a comparison result; an integrating capacitor connected to an input of the comparator; and a switched capacitor circuit connected at a first end to the input node, the input of the comparator, and the integrating capacitor, and connected at a second end to an output of the comparator. The current mode sigma-delta modulator is a component of an analog-to-digital converter.
