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 data transmission rate; the maximum amount of information (bits/second) that can be transmitted along a channel is called band width.
Disadvantage of low Power Factor We know that P = V I cos φ, for particular amount of power at constant voltage, Power (P) and voltage (V) in the above expression of

Experiencing a constant horizontal 1.10 m/s wind, a hot-air balloon ascends from the launch site at a constant vertical speed of 2.70 m/s. At a height of 202 m, the balloonist main
What is waveguide dispersion in optical fibres? Waveguide dispersion (Δτ w ): Waveguide dispersion occurs because of the dependence onto the velocity of propagation of every
A scalar function is given by f(x, y, z) = 2xy 2 + xyz 3 . Calculate the gradient of the function at the point (1, 1, 1).
When you are talking about relative velocity of A with respect B then it''s like you are observing the motion of A while standing on B. That is, with respect to you, B is at rest.
