摘　　要：提出了一种新型反相复合放大器电路，建立了该放大器电路在直流和交流下的传递函数的数学模型，并分析了直流放大时电路的误差，交流放大时电路的幅频误差、相频误差及失调引起的误差。The paper gives a novel inverting composite amplifier, establishes the mathematical model of the transform function of the kind amplifier's circuit, also analyzes the circuit error of direct current signal, the amplitude error and phase error of alternating current signal and the error produced by offset when the amplifier is at work.

关 键 词：复合放大器 反相放大器 幅频误差 相频误差
