Abstract

A low-power capacitive-feedback amplifier IC for neural SoCs in medical implant devices using 0.18μm CMOS technology is presented. The proposed neural amplifier, which is based on the source-degenerated folded-cascoded OTA, achieves 40 dB of voltage gain and integrated input-referred noise of 4.3 μVrms in the range of 1 Hz to 10 kHz while dissipating 2.2 μA of current from a 1 V supply. The designed amplifier IC achieves the noise efficiency factor of 3.07 and occupies 0.136 mm2 of area.
