Abstract
A unique transistor model and methods for analyzing the model are disclosed. The transistor model of the present invention is simple and requires specification of a minimal number of parameters to simulate transistor operation. Three analysis methods are disclosed, each having unique circumstances for application A first method is premised on sampling all waveforms in the circuit and determining the operating point of the transistor. The first method assumes an input of an arbitrary periodic waveform. The first method is very flexible and may be used with a wide range of models other than the disclosed model. A second and a third method are premised on input and output waveform clipping. The second method assumes a single tone input into the transistor. The third method is a combination of features from the first and second methods. The third method is computationally efficient and assumes an arbitrary periodic input waveform.
