SIM D *6.49 Consider the circuit of Fig. P6.48 for the case VBB = VCC. If the BJT is saturated, use the equivalent circuit of Fig. 6.21 to derive an expression for βforced in terms of VCC and (RB/RC). Also derive an expression for the total power dissipated in the circuit. For VCC = 5V, design the circuit so that it operates at a forced β as close to 10 as possible while limiting the power dissipation to no larger than 20 mW. Use 1% resistors (see Appendix J).
