What is the relation between the efficiency of class B and class A power amplifiers:

Calculate the closed loop gain of an amplifier if a negative feedback factor β of 0.1 is used and the open loop gain of the amplifier is 175.

Crossover distortion behavior is characteristic of which output stage?

What happens to the drain current of a MOSFET if the channel length of the MOSFET is reduced?

A band-pass signal has significant frequency component in the range of 1.5 MHz to 2 MHz. If the signal is to be reconstructed from its samples, the minimum sampling frequency will be

A step-down transformer is used to reduce the main supply of 220 V to 10 V. If the primary current is 5 A and the secondary current is 100 A, calculate the efficiency of the transformer.

For an NMOSFET operating in the saturation region:

a. What is the effect on the drain current if the width of the MOSFET is increased?

b. What is the effect on the drain current if VDS is increased (assuming LAMBDA ≠ 0)?

There is an amplifier with a voltage gain of 60 dB and an output impedance Z_o = 12 kΩ. It is required to modify the output impedance to 600 Ω by applying negative feedback. Calculate the value of the feedback factor. Also, find the percentage change in the overall gain for a 10% change in the gain of the internal amplifier.
