Gummel plot

In electronics, the Gummel plot is the combined plot of the base and collector electric currents,

, of a bipolar transistor vs. the base–emitter voltage,

This plot is very useful in device characterization because it reflects on the quality of the emitter–base junction while the base–collector bias,

A number of other device parameters can be garnered either quantitatively or qualitatively directly from the Gummel plot:[1] Sometimes the DC current gain,
