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.

用于神经信号处理的25hz低频截止的单片带通放大器

报道了一种用于神经信号记录的单片带通放大器。放大器的低频截止使用低gm反馈和500pa的偏置电流来获得可预测的响应，而无需片外组件或校准。在25 Hz至15 kHz范围内，测量的通带增益为37.9 dB，输入参考噪声为1.04 muV rms，功耗为162 muW, 0.5 μ m CMOS的芯片面积为0.13 mm2。
