Deep Level Bulk Traps (EL2) - AC Analysis : Deep Level Bulk Traps (EL2) - AC Analysis

Requires: SSuprem 4/Blaze
Minimum Versions: Atlas 5.24.1.R

This example is based on the structure created in example 4 within the MESFET section - the trap simulation is now performed in ac mode.

The AC simulation uses the same initial point as the previous two cases. The gate is grounded and the drain is at 0.5V. An AC signal is applied at this point to each contact in turn. The frequency of this AC signal is then ramped from 1MHz to over 10GHz. The fstep parameter sets the step size of the frequency change. However the parameter mult.f means fstep is applied as a multiplier to the frequency rather than as a sum.

As described in example 2 in this section, the s.param command on the log statement is used to specify the output of s-parameters.
