DC and Bias Point Simulations > BJT Stability vs. Bias

Description

This simulates the S-parameters of a transistor, with the base current swept and the emitter bias voltage constant, to determine the stability factors as a function of base current. It should help you determine the dependence of the stability factor on the bias point.

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

• Stability measure, B1, versus base current and frequency
• Stability factor, K, versus base current and frequency
• Geometrically-derived load stability factor, mu, versus base current and frequency
• Geometrically-derived source stability factor, mu_prime, versus base current and frequency
