基于PSpice的函数发生器的设计与仿真分析

函数发生器的作用是产生不同幅度和频率的波形.为了设计能产生正弦波、方波、三角波的函数发生器电路,采用理论分析与软件仿真结合的设计方法,在OrCAD/PSpice环境中建立仿真模型,对各功能电路进行仿真分析实验.实验中得到三种波形并对起振时间和振荡频率等参数进行测量,并与理论值做出比较.结果表明,利用PSpice对电子电路特性进行仿真分析,易于实现,为电路设计提供可靠的理论依据.

PSpice function generator-based design and simulation analysis

The role of the function generator is produce different amplitude and frequency of the wave- form. To design function generator circuit which can produce sine , square, triangle wave , using combination of theoretical analysis simulation; create a simulation model in the OrCAD/PSpice environment , and do simulation experiments analysis to each functional circuit , get three kinds of waveform and measure the start-up time and oscillation frequency and other parameters , and compare with the theoretical value; the results show that electronic circuit characteristics simulation analysis using Pspice, easy to implement, and provide reliable theoretical basis for circuit design.
