Field-effect transistor, Physics

Assignment Help:

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?
