In the npn – pnp amplifier project, we determine VAFn directly through a gain measurement for a circuit configuration in which (C.51) is valid. The requirement that RBp ≈ 0 will be implemented by shunting the base of the pnp transistor to ground with a capacitor, Cb, as shown in Fig. C.12. The capacitor must be sufficiently large to hold the base at ground at the frequency of the gain measurements.

The expression to determine the required value of ...
