Repeat Problem 8.11 if the output signal is taken as the voltage at the emitter of Q₃.

Repeat Problem 8.11

The half-circuit of a balanced monolithic series-series triple is shown in Fig. 8.18a. Calculate the input impedance, output impedance, loop gain, and overall gain of the half-circuit at low frequencies using the following data:

R_E1 = R_E2 = 290 R_F = 1.9kΩ

R_L1 = 10.6k R_L2 = 6kΩ

For the transistors, I_C1 = 0.5mA, I_C2 = 0.77 mA, I_C3 = 0.73 mA, β = 120, r_b = 0, and V_A = 40 V.
