Question Paper
1. State whether the following statements are true or false:
The number of free electrons in conductors are plenty whereas in case of insulators they are negligible.
Position of holes keeps changing.
In a p-n junction, holes diffuse from the p-region to n-region because the holes concentration in the p-region is greater as compared to n-region.
A zener diode has a high amplification.
The current ICBO flows in the collector and base leads.
A transistor is said to be in quiescent state when it is unbiased.
The filter circuit that is effective for a very large value of load resistance is capacitive filter.
The UJT can tum ON only when the emitter base junction is reverse biased.
In a N-channel depletion type MOSFET the N-type substrate acts as the channel.
A tunnel diode uses a high doping level to provide a narrow junction.
What is an insulator? What is Fermi level Why does a pure semiconductor behave like an insulator at absolute zero temperature?
Giving relevant defining equations, explain the phenomenon of drift and diffusion associated with carrier movement in semiconductors.
What is a 'barrier potential' in a p-n junction What happens when the n-type material is made more positive than the p-type material by an external voltage source What ultimately happens, if the applied voltage is gradually increased?
Describe the principle and working of tunnel diode.
Draw Ebers-Moll model of a transistor and explain transistor action. Derive the current equation for IE,IB and Ic.
In the CE configuration, collector supply voltage Vcc =10 V,load resistance RC is 8 k.ohm Draw dc load line. Determine the operating point for zero signal, if the base current is 15 MA and B is 40.
Draw the circuit of a transistor in common emitter configuration. Sketch the output characteristics. Indicate the active, saturation and cut-off regions.
Draw a self-bias circuit. Explain why such a circuit is an improvement over the fixed bias circuit as far as stability is concerned.
Describe briefly the construction and operation of a MOSFET in depletion region.
Explaining the feature of JFET, draw the drain characteristics. Show all regions of operations.
Explain the working of a series regulated power supply with the help of a diagram.
Explain with the help of a neat diagram, the operation of a bridge rectifier.
