Homework Answers
Ans 2) The operation in a Class B amplifier has Zero DC bias. It is beacuse the transistors are biased at the cutoff. Therefore the transistor conducts only when the maximum input voltages or the maximum +ve and - ve voltages are greater than the Base-Emitter voltage.

The balanced positive and negative DC power supplies of an ideal class AB amplifier are set at Vcc = +18 volts and Vss=-18 volts. For a sinusodal input signal that results in maximum sinusoidal output voltage across the resistive load RL = 30.0 ohms, the average power dissipated by the resistive load RL is determined as nearest to which of the following answers:- O 1.2 watts 3.8 watts O 5.4 watts O 11.25 watts 13.1 watts

a) What is "power-conversion efficiency' of an output stage? Comparo the class-A and class-B amplifier output stages with rospect to their power-conversion officiencies. b) Assume that an emitter follower 9, is used as a class-A output stago, with the constant current supplied by another transistor 2. (as in Figure Q.4.a). Let Vcc=16V, 1 =100mA, and R=10002. If the output voltage is an 4-V-peak sinusoid, find the power conversion efficiency.

Introduction The purpose of this project is to design, simulate, analyze, implement, and test a single-supply, multistage, transistor amplifier which fulfills a set of specifications. For this project, the pre-lab shall be treated as your formal design report and therefore must be much more detailed than usual (please see Evaluation heading on the next page of this document). The report shall be submitted to the TA by the deadline. The report is an individual assignment. Specifications • Power supply: +???...
