It consists of two parts: a transconductance amplifier and a transresistance amplifier formed by resistor feedback. The combination of these two amplifier forms a voltage amplifier with low output impedance, and the pole at the output node is hardly affected by the loading capacitor. 它由两部分组成:前面为跨导放大器,后面则是由电阻反馈形成的跨阻放大器,两种放大器的组合构成了具有高输入阻抗、低输出阻抗的电压放大器。
