介绍了利用ＰＳＰＩＣＥ程序对防窃电电路参数进行分析设计的新想法，以达到防窃电电路在生产加工过程中能对其参数进行预测分析，找出影响参数的元器件的选值，从而达到优化设计的目的；同时也可以做为防窃电电路生产过程质量控制的一个方法． Introduced the PSPICE program to analyze the anti-tamper circuit parameters of the new idea to prevent anti-tampering circuit in the production process can predict its parameters, to identify the parameters of the components of the selected value, so as to achieve Optimize the design of the purpose; but also can be used as anti-stealing circuit quality control of the production process as a method.
