摘　　要：本文利用THS4130芯片设计了一种结构简单、精确度高的单端转差模信号源电路,该电路还可同时输出共模信号。笔者计算了电路参数,并在Mulitisim软件中完成了仿真验证。最后,在PCB板上实现了该电路。实践证明,该电路可将常见的单端信号源转换成良好的差模、共模信号,可提供高校本科生差模放大电路实验所需的可靠差模信号源。This article designed a simple structured,high accurate single end turn differential mode signal source circuit with the chip THS4130. Besides,the circuit can also output common mode signals at the same time. The authors calculated the circuit parameters and completed the simulation with the Mulitisim software. Finally,a PCB board is made and the output signal is verified. It is proved that this circuit can convert commonly single ended source to a good difference mode and common mode signal,and can be useful for the undergraduate students.
