A 3.6 μW 60 nV/sqrtHz Capacitively-Coupled Instrumentation Amplifier for Biopotential Signal Recordings

This paper presents a low-power low-noise instrumentation ampli ̄er (IA) intended for biopotential signal recordings. The IA is designed based on a capacitively-coupled topology, which achieves wide input common-mode range, high common-mode rejection ratio (CMRR) and low power consumption. To reduce low-frequency noise and output ripple at the same time, a… CONTINUE READING
