本文提出了一种2.2噪声效率因子（NEF）仪表放大器的神经记录应用。设计了一个基于MOS C-V特性的参量放大器作为前置放大级，使后级的输入参考噪声降低了3.4倍，通过对输入信号进行过采样使采样噪声最小化，并采用8相软充电技术降低了开关功耗。
This paper proposes a 2.2 noise efficiency factor (NEF) instrumentation amplifier for neural recording applications. A parametric amplifier based on the MOS C-V characteristic is designed as a pre-amplifier stage, lowering the input referred noise of the following stages by 3.4 x Sampling noise is minimized by oversampling the input signal and switching power is reduced by adopting an 8-phase soft-charging technique.
