共射极和共集极放大器的放大系数,会由于集极一基极电容的反馈效应而在高频响应时严重下降(密勒效应)。这里介绍一种用低电源电阻来使这种效应
The amplification factor of the common-emitter and common-collector amplifiers is severely degraded (Miller effect) at high-frequency response due to the feedback effect of the collector-base capacitance. Here’s a low supply resistance to make this effect
