WebIn many applications, a “bidirectional” emitter follower circuit (that can source and sink currents with equal ease) is required, and this action can be obtained by using a complementary emitter follower configuration in which NPN and PNP emitter followers are effectively wired in series. Figures 19 to 21 show basic circuits of this type. WebThe emitter-follower of Fig. E2.2 has a voltage divider at its output. Assuming the same BJT parameters and using a dc analysis as in Example 2, 1, we get VBE = 0.82 V and IE = 4.95 mA. Consequently, VC = 6.1 V, but this does not affect the small-signal amplifier parameters (using the T model).
