Abstract

This paper presents a 8-channel bio-potential front-end with multi-channel common-mode replication(MC-CMR) . The front-end has been implemented in a standard CMOS 0.18-µm process, and the measurement results show that the amplifier has an adjustable gain of 46 to 64 dB, the input reference noise within 1Hz to 1k Hz is 1.62µVrms , TCMRR of the front-end is 100dB (at 50Hz). A single channel consumes 1.86µA at 1.8V supply voltage, and the NEF is 2.7.
