In this situation, the CMRR (common-mode rejection ratio) of the inputdifferential amplifier was unsatisfactory.
在这种情况下,输入差分放大器的CMRR 不令人满意。

For this, I adopt the new differentialinput stage to make input common mode range enlarged, and as far as possible not reduce its gain.
为此,采用了新的差分输入级,使共模范围增大,同时尽量不减少差分输入级的增益。

For improving the anti-interference ability of the amplifier, the DifferentialModeinput with high common mode restraining technology is adopted in amplifier circuits.
