WebApr 10, 2024 · You can use the following formula to calculate the parameter α: α = β β+1 α = β β + 1 As with the hybrid-π model, the T model can use either a voltage or a current as the variable that controls the current source. In the T model, the current source’s expression is either g m V BE (as shown above) or αI E: Using the Models Webwe get all possible values for I C and V CE for a given amplifier.
