Dear all,

I am designing rectifier for RFID tags. I need to calculate input impedance and input power.
I did PSS analysis and Transient analysis. Since my rectifier is non-linear circuit. I need to match it with antenna.
So, i need matching networks. I am using cadence software with UMC 180nm.

I calculated input impedance through many ways. i am getting different results. Now i am not clear which impedance is correct.
I need to calculate real part and img part of impedance then i could make matching network.

Some one told me to calculate impedance using DFT in cadence calculator. will it work?

can someone tell me the right way so that i could get correct values.
