In this situation, the CMRR (common-moderejection ratio) of the input differential amplifier was unsatisfactory.
在这种情况下,输入差分放大器的CMRR 不令人满意。
2
The MCU replaces the operational amplifier circuit so as to strengthen the system of common-moderejection, improve the problems of weak signal transmission.
更换了运算放大调理电路增强了系统的共模抑制能力,改善微弱信号传输中的问题;
3
The main design work as follow: the former disposal circuits were designed, and the circuit possesses very high input resistance, common-moderejection and voltage gain;
