摘要

A two-channel micro-power incremental ADC, designed for biosensor interface circuits, is reported. It uses a noise-coupled multi-bit delta-sigma loop, integrated with a novel digital decimation filter operating in near-threshold. It was realized in the IBM 90 nm CMOS technology. The fabricated 90nm CMOS prototype device, for a 1 V _pp differential input range, experimentally shows a 74dB SNDR up to 2 kHz (1 kHz/channel) signal bandwidth. The total measured power consumption of the modulator is 13.5 μW.
