D 6.55 Consider the circuit in Fig. P6.51 with the base voltage VB obtained using a voltage divider across the 5-V supply. Assuming the transistor β to be very large (i.e., ignoring the base current), design the voltage divider to obtain VB = 1.5 V. Design for a 0.1-mA current in the voltage divider. Now, if the BJT β = 100, analyze the circuit to determine the collector current and the collector voltage. R1 = 35 kΩ, R2 = 15 kΩ; 0.078 mA; 4.22 V
