6.55 Consider the circuit in Fig. P6.51 with the base voltage V B obtained using a voltage divider across the 3-V supply. Assuming the transistor β to be very large (i.e., ignoring the base current), design the voltage divider to obtain V B = 1.2 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.
