Response to the following problem:
For the circuit in Figure , the transistor parameters are β = 120, VBE (on) = 0.7 V, and VA = 80 V. The circuit parameters are VCC = 3.3 V, VBB = 1.10 V, RC = 4 kΩ , and RB = 110 k Ω.
(a) Determine the hybrid-π parameters.
(b) Find the small-signal voltage gain Av = vo/vs.
(c) If the time-varying output signal is given by vo = 0.5 sin(100t) V, what is vs(t)?
