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?
Can ever the whole charge of a body be transferred
Unit of Charges: The S.I unit of charge is Coulumb represented by "c".
The measurements taken in Ramdesns eyepiece more worthy (reliable) than Huygens eyepiece. Why? Describe critical angle. show its relationship with refractive index.
Q. What is the Newton meter? Answer:- A unit of energy is as well known as a Joule. When a force of 1 Newton is used on an object for a distance of 1 meter then 1 Joule of
A ball of mass 0.7 kg is dropped vertically from a height of 10 m onto a concrete floor. The ball is observed to bounce a number of times before coming to rest. The coefficient of
Explain the Electromagnetic Induction The force exerted on an electric charge moving in a magnetic field leads to the idea of magnets being able to produce electricity as well
Optical interference process is broadly divided into two categories namely (i) division of wave front (ii) division of amplitude. Give one example for each category of interference
