Abstract

When an active circuit is designed roughly, the CAD tool-PSPICE can be used to find the frequency responses of its transfer function with nonideal active devices whether it is stable or not. We may take adequate data to use curve-fitting method to obtain the transfer function as accurate as possible, and then use numerical method to find whether it has right half-plane poles. An example is given to verify the proposed method
