Problem 1:

Consider the circuit below. V_cc = 12V, R_B1 = 120kΩ, R_B2 = 40 kΩ, R_B3 = 120 kΩ, RB4 = 20kΩ, RE1 = 3kΩ, RE2 = 1kΩ, RC2= 10 kΩ, Rcz = 0 and β = 50.

a. Calculate the collector current and emitter voltage for both transistors. Neglect Early effect

b. Draw the small signal equivalent circuit.

c. Calculate RIN2, RIN, ROUT

d. Calculate the overall gain with load of the amplifier if RL = 10 kΩ.
