You have to
design a circuit that has an interface to the outside world made
up of 5 wires:
a. One wire connects to ground.
b. One wire connects to a single supply voltage, Vsupply. (See Design Constraints below).
c. One wire connects to a control signal. During testing, this signal is only allowed to have values 0 or +5V.
d. The remaining two wires v1 and v2 are what the switch is supposed to connect. If Vcontrol = 0V
then the switch should be closed and ideally v1=v2 . If Vcontrol = +5V then the switch is open
and ideally i1=i2=0 where i1 and i2 are the currents into each of the two wires v1 and v2 .
Design Constraints
1. You are limited to the use of a single dc power supply. Vsupply ≤ +5V .
2. You are allowed the use of MOSFETs, diodes, resistors, and capacitors that are available in your
component kits.
3. You have a single control voltage. The function of the control voltage is as described above for
each type of switch.
