  • Abstract
    A monolithic bandpass amplifier for neural signal recording is reported. The low-frequency cutoff of the amplifier is obtained using low-gm feedback and a bias current of 500 pA to obtain a predictable response without off-chip components or calibration. The measured passband gain is 37.9 dB from 25 Hz to 15 kHz and input-referred noise is 1.04 muV rms, using a power consumption of 162 muW and a die area of 0.13 mm2 in 0.5-mum CMOS.
