D8.4 Assuming the availability of BJTs with scale currents IS = 10−15A, β = 100, and VA = 50 V, design the current-source circuit of Fig. 8.9 to provide an output current IO = 0.5 mA at VO = 2 V. The power supply VCC = 5 V. Give the values of IREF, R, and VOmin. Also, find IO at VO = 5 V.
0.497 mA; 8.71 kΩ; 0.3 V; 0.53 mA
