摘　　要：设计了一种神经电极放大器系统,用于在手术中对于病患某一神经区域进行监测。系统可产生类神经电信号刺激肌肉,同时采取相应的肌电信号进行分析,由刺激发生器、前置输入放大器、带通选频网络、缓冲放大器和信号显示电路等组成,电路基本上采用模拟电路构成,总体放大增益可达到960～10000。An amplifier system for neural electrode is designed and used in the monitoring of the brain neural region during surgery process. The system can produce neuroid electric signals to stimulate muscle, at the same time take corresponding EMG signals for analysis. It is composed of stimulation generator, pre-amplifier, band-pass frequency selection network, buffer amplifiers, signal display circuit, etc. The system basically uses analogue circuits, and the overall amplification gain reaches 960 to 10,000.
