**6.63 It is required to design the circuit in Fig. P6.63 so that a current of 1 mA is established in the emitter and a voltage of −1 V appears at the collector. The transistor type used has a nominal β of 100. However, the β value can be as low as 50 and as high as 150. Your design should ensure that the specified emitter current is obtained when β=100 and that at the extreme values of β the emitter current does not change by more than 10% of its nominal value. Also, design for as large a value for R B as possible. Give the values of R B , R E , and R C to the nearest kilohm. What is the expected range of collector current and collector voltage corresponding to the full range of β values?
