Abstract

A delta sigma modulator includes a comparator circuit with an output that provides a digital signal which is indicative of a voltage of an a signal received at its input terminal. The modulator includes a continuous-time path from the modular input terminal to an input terminal of a comparator of the comparator circuit. The modulator includes a first feedback loop connected to a first integrating node of the path that provides a first comparator circuit output controlled feedback current and a second a second feedback loop that provides a second comparator circuit output controlled feedback current to a second integrating node of the path that is connected to the input terminal of the comparator and connected to a capacitor.
