4.(20%) For the CC-CB amplifier of Figure 4, let I = 1 mA, β = 100, Cπ= 8 pF, Cμ = 3 pF,Rig = 15 kΩ, RL= 20 kΩ, and thermal voltage is 25.9 mV. Find (a) the low-frequency overall voltage gain AM, (b) the frequencies of the poles for the high frequency response, and (c) the 3-dB frequency fi. All BJIs have the same β, Cπ and Cμ. (5%, 10%, 5%)
