Small Signal (AC) Bipolar Parameters from SPICE Parameters
Small Signal (AC) Bipolar Parameters from SPICE Parameters
This Demonstration computes a group of high-frequency bipolar junction transistor parameters (such as "ft", the unity gain bandwidth frequency) from the appropriate SPICE model parameters. The result is plotted on a graph versus either collector current (Ic) or voltage collector to emitter (Vce), whichever is relevant. It also gives a numerical result for the parameter above the graph for a particular value of Ic and Vce set by their sliders.
