Redraw the current source a, but with R1 replaced by a 6.2-V Zener diode (cathode at the top) having rz 5 20 V, and by changing R2 to 2.0 kV. The function of the Zener diode is to stabilize the source against possible variations in the supply voltage VCC. This circuit could be used to provide the emitter bias for the pnp BJT amplifi ers discussed in Sections 8 and 9, here referred to simply as load (LD). Its output current is IO 5 F(VZ 2 VEB(on))yRE > (6.2 2 0.7)y10 5 0.55 mA. Assuming the BJT has F 5 100 and VA 5 100 V, fi nd the Load Regulation DIOyDVL and the LineRegulation DIOyDVCC of the circuit.
