Abstract

This paper presents a 15-bit ΔΣ ADC with 10kHz-BW which can handle 30V CM voltages with high AC CMRR (in excess of 115dB at 10kHz) while operating from a 1.8 V supply. An HV capacitively-coupled chopper at its input enables the accurate sampling of input signals beyond the supply rails. Chopping is used to mitigate the ADC's offset and to enhance its CMRR, especially at high frequencies.
