1. A zener diode regulator in figure, is to be designed to meet the
specifications : IL = 10 mA, Vo = 10 volts, and Vin varies from
30 volts to 50 volts. The zener diode has Vz = 10 volts, and
Izk (knee current) = 1 mA. For satisfactory operation
2. Consider the following statements in connection with the CMOS
inverter in figure, where both the MOSFETs are of enhancement
type and both have a threshold voltage of 2 volts.
S1 : T1 conducts when Vi >= 2 volts.
S2 : T1 is always in saturation when Vo = 0 volts.
Which of the following is correct.
