摘　　要：简述一种典型的差分输入差分输出放大电路的设计、仿真和测试方法,讨论其设计原理及需要解决的问题。重点讲述差分滤波器的设计和计算,指出与单端放大电路在设计和测试中的不同之处,并结合实际工作中的经验,就直流信号和交流信号的测试分别给出了一种简易案例。The design,simulation and testing of an amplifier with differential input and differential output are briefly described. Its operating principles and some problems in applications are discussed,and the corresponding measures are given. Design calculation of the differential filter is the key point of this paper. The differences between the differential amplifier and the single-ended amplifier are listed in the design and testing aspects. According to experience in practical work,this paper presents a simple case of testing of DC signal and AC signal,respectively.
