A 90nm CMOS bio-potential signal readout front-end with improved powerline interference rejection


This paper describes a 90nm CMOS low-noise low-power biopotential signal readout front-end (RFE). The front-stage instrumentation amplifier (IA) features a chopper; an AC-coupler and a novel chopper notch filter for minimizing the dc-offset; transistors' flicker noise and 50Hz powerline interference concurrently. A noise-aware transistor selection (thin… (More)
