DC and Bias Point Simulations > BJT Ft vs. Bias

Description

This simulates a device's ft, the frequency at which the short-circuit current gain drops to unity, versus bias current, for a particular value of VCE. It should help you determine how high in frequency a device can be used.
Needed to Use Schematic
Nonlinear BJT model

Main Schematic Settings

VCE, base current sweep limits, and frequency range for S-parameter simulation

Data Display Outputs

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