In the circuit given in the figure, Vcc = 15 V, R1 = R2 = 10kΩ, RE = 1KΩ, RL = 0.5kΩ and transistor parameters are given as VBE = 0.7V, ßdc = ß0 = 100. a. Calculate the values of DC bias currents and voltages (IBQ, ICQ and VCEQ). b. Draw the small signal equivalent circuit of the circuit using the hybrid model of the transistor. c. Derive the input impedance expression of the circuit and calculate its value. d. Derive the AVI and AVG voltage gain expressions and calculate their values. e. Derive the current gain expression AI = I0 / Ii and calculate its value. Compare this value you have calculated with the value you will calculate using the expression Aİ = Zi AVI / RL.
