Below I am providing you some questions of from question paper of Electronics and Communication Engineering 2nd Year Exam Papers and attaching a PDF attachment which has detail information regarding this that you can down load for free:

1. (a) With the help of necessary equations, discuss the variation of AI ,AV ,Ri, and
Ro with RS and RL in Common Emitter configuration.
(b) For a CE configuration, what is the maximum value of RS for which Ro differs
by no more than 10 percent of its value for RS = 0. The h-parameter values
are hfe = 50, hie =1.1K
, hre = 2.5x10−4, hoe = 25 µA/V. [10+6]
2. A two-stage amplifier circuit (CE-CC configuration) is shown in figure 2. The h-
parameter values are hfe = 50, hie=2 K
, hre =6× 10−4, hoe = 25µA/V.
hfc = -51, hic =2 K
, hrc = 1, hoc = 25µ A/V.
Find the input and output impedances and individual, as well as overall voltage
and current gains.
