EECE 310 Homework 1 Solution, Fall 2011

American University of Beirut Department of Electrical and Computer Engineering EECE 310 – Electronics Fall 2011 – 2012 Homework 1 Problem 1 a) for . At , At , . Solving gives or . Since at Thus the saturation levels are at , and at V V b) To obtain , the required input voltage is: Since , √ c) Av vI 3.77 ; . In dB B. d) ( ( ) ) DC component= ; where . 2 1 A A so that Problem 2 a) The output saturation is V. The peak-to-peak value of the largest sinusoidal wave is 0.5V. Since the amplifier has linear transfer function V/V, in dB b) The output power is ( √ ) =1.89 W. c) The power gain is W/W. In dB, dB. A/A. In dB, . d) Pdc=12.7*200+12.7*200=5080mW. =37.2%.
