(a) Design a simple PNP current source to give an output current of IO = 0.5 mA (nominal value). The transistor parameters are f = 50, VEE = 10 V, VCC = 10V, |VBE| = 0.7 V, |VCEsat| = 0.3 V and VA = 50 V (for all transistors)
(b) Is Q1 in the active region? Why or why not?
(c) Is Q2 in the active region? Why or why not?
(d) Calculate the output resistance of the current source.
(e) What is the change in IO for a 1 V change in VO?
