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?
Coordinate System for Circular Motion In physics and circular motion is a movement of an object that was along the circumference of a circle or rotation along a circular path.
why we use compensater??
give the complete explaination with design formulae of single pv cell?
Advantages of induction motors 1. Simple design. 2. Low cost compared to other motors of the similar capacity. 3. High overload capacity. 4. Very rugged construction.
The line integral of the magnetic flux about a closed curve is proportional to the algebraic total of electric currents passing through that closed curve; or, in differential form,
Radio Waves: Radio waves are electromagnetic waves with large range of wavelength from a few millimetres to many meters.
Light is quantized. Photons are light quanta. It has zero REST mass. Therefore, it always travels at maximum speed permitted by relativity.
Given below are two electric circuits A and B Measure the ratio of power factor of the circuit B to the power factor of circuit A.
Doppler effect (C.J. Doppler) Waves emitted through a moving object as attained by an observer will be blueshifted (compressed) if approaching, redshifted (elongated) if reced
