Hi Crystal, It depends upon which simulator you are using? ADS make it very simple = to use any frequency dependent data with its High Frequency SPICE = simulator. It will allow you to define Inductance value as a function of = global variable "freq" either using a variable equation or as a tabular = data and include in time domain simulation directly. If you have access = to ADS, please let me know and I will send you some sample examples?

Suppose i have the inductance value in frequency domain, how can i use it in spice = simulation? Thanks a lot!
