Question: For the AC equivalent circuit of a common-emitter BJT amplifier shown in Figure 1, assume that VCC = 10 V, VBE = 0.7 V, RS = 5 kΩ, RB = 100 kΩ, RL = 1 kΩ, Cb'e = 2 pF, Ccb′ = 1 pF, and CL = 1 pF. Assume bias current IB = 25 μA, Boltzmann's constant k = 1.38×10−23 J/K, q = 1.6 ×10−19 C, T = 300 K, VT = 26 mV, β = 100, rbb' = 100 Ω, and ignore ro. Assuming the equivalent noise bandwidth is 100 kHz, and neglecting the flicker noise and capacitive effect. Note: For the BJT biased on the forward active region: rπ = VT/IB, gm = IC/VT. (a) Calculate the total equivalent input rms noise voltage and current by looking into node a. (b) Calculate the total equivalent input rms noise voltage and current by looking into node b. (c) Discuss if a transformer (with turn ratio I:N) can be incorporated into point b to minimize the total input referred noise? If yes, what is the N to be? Figure 1
