Gummel–Poon model

The Gummel–Poon model is a model of the bipolar junction transistor. It was first described in a paper published by Hermann K. Gummel and H.C. Poon at Bell Labs in 1970^[1].

The Gummel–Poon model and modern variants of it are widely used via incorporation in the popular circuit simulators known as SPICE. A significant effect included in the Gummel–Poon model is the DC current variation of the transistor $\beta _{\mathrm {F} }$ and $\beta _{\mathrm {R} }$ . When certain parameters are omitted, the Gummel–Poon model reverts to the simpler Ebers–Moll model.
