As you asking for the previous year question paper of the PGCET Examination the questions are as follow:


Epitaxial growth is used in integrated circuit
(A) because it produces low parasitic capacitance
(B) because it yields back-to-back isolating junctions
(C) to grow single crystal n - doped silicon on a single-crystal p - type substrate
(D) to grow selectively single-crystal p - doped silicon of one resistivity on p - type substrate of a
different resistivity.


The chemical reaction involved in epitaxial growth in IC chips takes place at a temperature of about
(A) 500° C (B) 800° C
(C) 1200° C (D) 2000° C


Assertion (A) In the self bias CE transistor amplifier a single battery is used.
Reason (R) The collector base junction is forward biased by V
CC
.
Chose the correct option:
(A) Both A and R individually true and R is the correct explanation of A.
(B) Both A and R individually true and but R is not the correct explanation of A.
(C) A is true but R is false
(D) A is false


The address bus width of a memory of size 1024 ´ 8 bits is
(A) 10 bits (B) 13 bits
(C) 8 bits (D) 18 bits


Consider the List I and List II
List I List II
P. Derivative control 1. Improved overshoot response
Q. Integral control 2. Less steady state errors
R. Rate feed back control 3. Less stable
S. Proportional control 4. More damping
The correct match is
P Q R S
(A) 1 2 3 4
(B) 4 3 1 2
(C) 2 3 1 4
(D) 1 2 4 3

In TDM non essential frequency components of the modulating signal are removed by
(A) sampler (B) attenuator
(C) pre-alias filter (C) modulator


Two dissimilar antennas having their maximum directivities equal,
(A) must have their beamwidths also equal.
(B) can not have their beamwidths equal because they are dissimilar antenna.
(C) may not necessarily have their maximum power gain equal.
(D) must have their effective aperture areas ( capture areas) also equal.



The dominant mode in a rectangular waveguide is TE10because this mode has
(A) no attenuation (B) no cut-off
(C) no magnetic field component (D) the highest cut-off wavelength
