A) Design a MOSFET class B output stage to deliver an average power of 100W into a 16Ω load. Use a power supply voltage at least 3V greater than the peak sine wave output desired and rounded to the nearest appropriate volt. B) Calculate the peak current from each supply, the total supply power, and the power conversion efficiency. C) Calculate the maximum possible power dissipation in each transistor for a sine wave input.
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.

2. Consider a class B BJT output stage with a square wave output voltage of amplitude Vo across a load Ri. and employing power supplies Vss. Neglecting the effects of finite VBE and VCEs (i.e., assume both VBE and VcEsat are negligible small) determine the load power, the supply power, the power conversion efficiency, the maximum attainable power conversion efficiency and the corresponding value of Vo.

It is required to design a class B output stage to deliver an average power of 20 W to an 8-Ω load. The power supply is to be selected such that Vcc is about 5 V greater than the peak output voltage. This avoids transistor saturation and the associated nonlinear distortion, and allows for including short-circuit protection circuitry. (The latter will be discussed in Section 12.6.) Determine the supply voltage required the peak current drawn from each supply, the total...
