6.5 For the circuit in Figure 6.3, the transistor parameters are 8 = 120, VBE (on)=0.7 V, and VA = 80 V. The circuit parameters are Vcc = 3.3 V, VBB 1.10 V, RC 4k, and RB = 110k. (a) Determine the hybrid- parameters. (b) Find the small-signal voltage gain A, vo/vs. (c) If the time-varying output signal is given by v₁ = 0.5 sin(100r) V, what is u,(t)? = =
