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?
Laplace equation (P. Laplace): For steady-state heat conduction in one dimension, the temperature distribution is the resolution to Laplace's equation, that states the second
explain the negative result of speciale theory of relativity
Draw the electric field figure as viewed by a person positioned on the positive x-axis who is looking back toward the origin for the case of an electric field characterized by the
Explain the Conservation of Momentum In a collision, energy is not all time conserved, if not the collision is totally elastic (all stored energy is turned into kinetic energy
Superposition principle The general idea is that, while a number of influences are working on a system, the total influence on that system is just the sum of the individual in
how Michelson interferometer can be used to measure the wavelength of sodium light.
Describe a) Potential difference between two points V, B) Intensity of electric field E. Derive the relation between them.
The velocity with which the group of waves travels is called as group velocity or the velocity with which a ray packet goes is called as group velocity
1) The potential energy between two atoms can be represented as follows: where A and B are constants and r the interatomic separation distance in metres. Plot the potential ene
Explain the Vector Addition of Velocity Of course the velocity is relative to how you indicate the position d. If you are moving in water that is itself moving, then your full
