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.
