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 C_jc or R_bb, but these items are easily added later, and there are times you would want to perform an analysis without them. C_jc is included in the equation for f_t (and therefore T_t ) so the frequency response for the model has not been compromised. The author has included R_eb 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.
