我们描述了一种植入式神经电图（ENG）放大器，专门用于失禁和其他功能性电刺激应用。该放大器的特点是一种新颖简单的被动技术，用于消除使用三极性袖带电极的神经记录系统中的肌电（EMG）干扰。介绍了前端系统模块（仪表放大器、后滤波器、整流器和可编程增益模块）。该放大器采用3 v 0.35 μ m BiCMOS工艺制作，并给出了初步测量结果。输入信号慢至1muv可以可靠地检测。
We describe an implantable electroneurogram (ENG) amplifier dedicated to incontinence and other functional electrical stimulation applications. The amplifier features a novel simple passive technique for removing myoelectric (EMG) interference in neural recording systems using tripolar cuff electrodes. The system blocks of the front- end (instrumentation amplifier, post-filter, rectifier and programmable gain block) are described. The amplifier was fabricated in a 3-V 0.35-mum BiCMOS process technology and preliminary measured results are presented. Input signals aslow as 1 muV can be reliably detected.
