DC and Bias Point Simulations > FET Ft vs. Bias

Description

This simulates a device's ft, the frequency at which the short-circuit current gain drops to unity, versus gate voltage, for a particular value of VDS. It should help you determine how high in frequency a device can be used.

Needed to Use Schematic

Nonlinear FET model.

Main Schematic Settings

VDS, gate voltage sweep limits, and frequency range for S-parameter simulation

Data Display Outputs

• Short circuit current gain versus gate voltage and frequency
• Frequency at which the short-circuit current gain drops to 0 dB, at the drain bias current specified by a movable marker
