Hi everyone,
Currently, I am working on NI AWR software to design a voltage controlled oscillator(VCO), in this process i have struck across a simulation of device input impedance as a function of drive level. This simulation process is done in the book name " Practical RF circuit design for modern wireless systems (volume-2)" by Rowan Gilmore and Les Besser. This simulation is performed in this between pages 412 to 414. I have attached the screenshot of those pages sequentially. I request the resource persons to kindly help me with this simulation process.
