If β_F= 100 for Q₁in Problem 5.1, calculate the average signal power delivered to Q₁by its driver stage if V_ois sinusoidal with an amplitude equal to the maximum possible before clipping occurs. Repeat for R_L= 10 k„¦. Thus calculate the power gain of the circuit.

Problem 5.1

A circuit as shown in Fig. 5.1 has V_CC = 15V, R₁ = R₂ = 0, R₃ = 5k„¦, R_L = 2k„¦, V_CE(sat) = 0.2 V, and V_BE(on) = 0.7 V. All device areas are equal.
