D 8.14 The current-source circuit of Fig. P8.14 uses a pair of matched pnp transistors having IS = 10−15A, β = 50, and |VA| = 50 V. Design the circuit to provide an output current IO = 1 mA at VO = 1 V. What values of IREF and R are needed? What is the maximum allowed value of VO while the current source continues to operate properly? What change occurs in IO corresponding to VO changing from the maximum positive value to –5 V? Hint: Adapt Eq. (8.21) for this case as:
