摘要

提出了一种低功耗低噪声电容耦合斩波仪表放大器,用于记录脑电图和心电图等神经信号。由于斩波技术,CCIA使用提出的自动零偏移抵消环路来减轻输出纹波。仿真结果表明,该CCIA的纹波衰减系数为41.24 dB,闭环增益为40 dB,带宽高达800 Hz。在50 Hz时,共模抑制比(CMRR)和功率抑制比分别为108.9和87 dB。所提出的CCIA采用0.18 μ m CMOS技术实现,占地面积仅为0.09平方毫米。来自1v电源的CCIA总电流消耗为1.2µA。

1.2 µW 41dB Ripple Attenuation Chopper Instrumentation Amplifier Using Auto-zero Offset Cancellation Loop
This paper presents a low power low noise capacitively-coupled chopper instrumentation amplifier (CCIA) for the recording of neural signals, including electroencephalogram (EEG) and electrocardiogram (ECG). Due to the chopping technique, CCIA uses the proposed auto-zero offset cancelation loop to mitigate the output ripple. According to simulation results, the proposed CCIA obtains a ripple attenuation factor of 41.24 dB, the closed-loop gain is 40 dB with a bandwidth up to 800 Hz. A common-mode rejection ratio (CMRR) and a power rejection ratio are 108.9 and 87 dB, respectively, at 50 Hz. The proposed CCIA, which was implemented in a 0.18 µm CMOS technology, occupies only 0.09 squared millimeters. The total current consumption of CCIA is 1.2 µA from a 1 V supply.
