[SOLVED] ADS Parasitic Capacitance Simulation

[striderZA]

Hi,

I have a VBIC model of a high-performance HBT (130 nm SiGe process) and I need to operate it where the parasitic capacitances are non-linear.

How would a simulation setup look like to determine these (specifically looking to determine Ccs and Ccb) at various bias points? I am using ADS 2020.

Cheers

If model parameters are permitted to be visible by Foundry, you can see some of them in DC Operating Point Option in ADS.Because they are generally embedded to the model and sometimes crypted so extracting intrinsic model parameters is not easy unless they are explicit.
