Abstract :
This paper presents for the first time analytic expressions for the optimum source and load impedance and associated large-signal gain for a transistor with series inductive and parallel capacitive feedback in addition to input and output capacitance. Both class A and B are considered. The computed results are shown to be in good agreement with experimental data.
