Question

Given the circuit in figure. Derive the formula of voltage gain and current gain using complete hybrid pi model. Draw the AC equivalent circuit

Emitter-Follower Z₁ C₁ Vcc RB B6 ΕΦ RE C₂ HH -o Vo Zo The emitter-follower configuration is frequently used for impedance-matching purposes. It presents a high impedance at the input and a low impedance at the output, which is the direct opposite of the standard fixed-bias configuration. The resulting effect is much the same as that obtained with a transformer, where a load is matched to the source impedance for maximum power transfer through the system.
