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. ![]() ![]()
