N2 - For Electrocardiogram (ECG) and electroencephalogram (EEG) recording application, this paper proposes an extremely low-power, low-noise analog front-end (AFE). Based on fully-integrated, high-pass, low-noise amplifier and inverter-based, low-power 2nd Sigma-Delta modulator, large output swing, excellent power efficiency and noise performance are achieved. The circuit is implemented in 0.13μm 1P8M Mixed-signal technology. The measurement results show in 0.6V power supply, input referred noise is 3.976μVrms and the noise efficient factor (NEF) is 3.658. Max Signal-to-Noise and Distortion Ratio (SNDR) is 66.7dB with 8.4μw power consumption. Compared with previous work, our design has the maximum SNDR and signal bandwidth, which meets the requirement of ECG/EEG recording application.
