It is useful to have two-port models available for the simplified transistor models introduced in Chapter 2. The model shown in Figure B-1 does not include any reference to Cjc or Rbb, but these items are easily added later, and there are times you would want to perform an analysis without them. Cjc is included in the equation for ft (and therefore Tt ) so the frequency response for the model has not been compromised. The author has included Reb because it is an important factor, and it is not always easily added. From this model, we want to derive the two-port h-parameter and the two-port s-parameter model.
