D7.41 Design the bias circuit of the CE amplifier of Fig. 7.58(a) to obtain IE = 0.5 mA and VC = +6 V. Design for a dc voltage at the base of 5 V and a current through RB2 of 50 µA. Let VCC = +15 V, β = 100, and VBE 0.7 V. Specify the values of RB1, RB2, RE, and RC. Also give the values of the BJT small-signal parameters gm, rπ, and ro at the bias point. (For the calculation of ro, let VA = 100 V.) RB1 = 182 kΩ; RB2 = 100 kΩ; RE = 8.6 kΩ; RC = 18 kΩ; gm = 20 mA/V, rπ = 5 kΩ, ro = 200 kΩ
