7.54 In the circuit shown in Fig. P7.54, the transistor has a β of 200. What is the dc voltage at the collector? Replacing the BJT with one of the hybrid-π models (neglecting ro), draw the equivalent circuit of the amplifier. Find the input resistances R ib and Rin and the overall voltage gain vo/vsig. For an output signal of ±0.4 V, what values of vsig and vb are required?
