High Voltage Delta-Sigma Modulator Analog-to-Digital Converter

A Delta-Sigma-Modulator (DSM) Analog-to-Digital Converter (ADC) and method of operating the same are provided. Generally, the ADC includes an input stage to receive an analog input voltage, a second order DSM coupled to the input stage, the DSM including a first integrator stage and a second integrator stage coupled in a cascade architecture, and a quantizer coupled to an output of the DSM operable to receive an output therefrom and to produce a multi-bit digital signal. The ADC has a fully differential architecture with the input stage coupling a positive input voltage and a negative input voltage to an integrator in the first integrator stage, the first integrator stage coupling a first positive output signal and a first negative output signal to a second integrator in the second integrator stage, and the second integrator stage coupling a second positive output signal and a second negative output signal to the quantizer.
