摘要
针对EWB软件仿真中出现的波形失真,通过比较不同条件下的输出波形,说明运算放大器的开环使用与比较器模型是不同的,证明EWB软件对电路进行仿真存在一定的局限,特别是非线性变换。
In consideration of the problems of waveform distortion in the simulation of EWB software, through contrast of waveforms under the different conditions, it indicates that the application of an open loop is different with that of a comparator model and there exists some limitations in circuit simulation by using EWB, especially for the nonlinear transformation.
