a) Sketch the small-signal equivalent circuit for a field-effect transistor (FET) and explain how it can be deduced from the properties of the real device.
b) Draw the circuit diagram for a common-source FET ac amplifier based on a voltage-divider bias scheme.
c) Draw the ac equivalent circuit for the above amplifier.
d) If the transconductance of the FET used in a common-source amplifier is 3.4 x 10-3 S and the load resistance is 4.7 kΩ, what is the approximate voltage gain of the amplifier?

A sky diver in free fall reaches a speed of 65.2 m/s when she opens her parachute. The parachute quickly slows her down to 7.30 m/s at a constant rate of 29.4 m/s 2 . During th
LENZ’S LAW A change of flux in a closed circuit induces an emf and sets up a current. The direction of this current is such that its magnetic field tends to oppose the c
