摘要: 在测试系统中,需要对微弱电压和电流信号进行放大和调理,因此,调理电路是其中的一个重要环节,对保证整个测试系统的可靠性起到十分关键的作用.采用计算机对调理电路进行仿真和热分析,能够在电路板研制成之前,先对调理电路的功能进行模拟、分析及优化有关参数,保证电路各项指标达到最优,这样,可以大大缩短电路的开发时间,节省研制经费,具有很高的实用价值.Abstract: In testing system, measuring small signals is necessary. The conditioning circuit is a crucial section, and its reliability has a great influence on the whole testing system. By using the method of computer simulation and thermal analysis, the functions of the circuit can be simulated and relevant parameters can be optimized previously to promote the circuit-s capability. By this means, the research time can be dramatically shortened and the expense can be more less. Therefore, these methods have a great value in practice.
