一种差动放大器输出转换电路的研究
资料介绍
设计了一种差动放大器的教学电路，研究了电阻负载和恒流源负载的差动放大器的特-}生。实验电路切换简单，测量方便，便于实践。使用Muhisim10对电路进行仿真，测算了两种差动放大器电路的静态工作点、差模电压放大倍数、共模电压放大倍数以及共模抑制比等。实验结果表明，该电路实现了双端输出转单端输出路，达到电路转换目的。
A teaching circuit is designed in this paper, aiming to study the characteristics of differential amplifier which adopts resistive load and constant current source load. The circuit is simple to switch, convenient to measure and helpful for the improvement of ability. It uses Multisim 10 to simulate the circuit to measure and calculate the quiescent operating point, the differential-mode voltage gain, common-mode voltage amplification, common-mode rejection ratio and some other characteristics of both differential amplifier circuit. The result shows that the circuit has implement the switch of double-ended output to single-ended output channel, and the purpose of circuit switching has been achieved.
