Hello,

I have a huge inverter in CMOS inside the chip. The inverter acts as a    
buffer and is driven by a clock source running at a GHz.    

I need to measure the output impedance of the inverter. So that I can
match this with the impedance of the PCB trace going to the SMA connector.

Can anyone help me in determing how to calculate the output impedance of  
the Inverter? I am using Spice for the simulation. 

Kind Regards

Himanshu Arora
