How to obtain high-frequency equivalent models of devices such as varistors and TVS transient diodes [Copy link]

The frequency response of electronic components will change at high frequencies, affecting the design of circuit functions. How to build high-frequency equivalent models of these components? My current idea is to measure the input and output through a two-port network, and then guess what is missing based on the low-frequency model. Please give me an idea. It would be best if there are books recommended on the study of equivalent models of components.

Where do you want to use these models?

For circuit simulation?

Thank you for your answer, but since I don't have prototypes of devices such as varistors, and I want to know their equivalent principles, these two Pspice books cannot meet my needs in this regard.

Device modeling can be done by yourself according to the book introduction

Thermistors cannot be found in the Multisim component library, so they are replaced by other

qwqwqw2088 Published on 2021-10-15 16:24 Device modeling can be based on the introduction in the book. You can write your own reference. You can't find thermistors in the component library of Multisim. You use its...

Thank you for your solution. I am now going to use microwave technology and actual tests to obtain the equivalent circuit diagram.
