The biopotential analog front-end (AFE) IC for measuring electroencephalogram (EEG) is proposed. The EEG AFE is based on the AC-coupled chopper stabilized instrumentation amplifier architecture to achieve the low noise. To increase the input impedance, the capacitive impedance boosting loop (CIBL) is proposed. The CIBL forms a positive feedback loop between input and output of the instrumentation amplifier without additional power consumption. The CIBL increases the input impedance from 644 MΩ to 3.5 GΩ, and enhances the CMRR from 133.4 dB to 139.1 dB, in simulation. The overall gain, the frequency response, and the input mismatches can be trimmed using programmable capacitors and programmable resistors. The EEG AFE is fabricated in 0.18 μm 1P6M CMOS process. The core chip size of the EEG AFE without I/O pads and sub-blocks is 3 mm2. The input referred noise is measured to be 0.205 μVrms in the bandwidth from 0.5 Hz to 100 Hz. The amplifying gain of the pass band is measured to be 78 dB.
