1.	Why the cost of MOSFET based power amplifier is less?(a) High impedance(b) Low capacitance(c) Low power dissipation(d) Lesser in sizeThis question was addressed to me by my school principal while I was bunking the class.My question is based upon Class D Amplifiers topic in section Power Amplifiers of Electronic Devices & Circuits
Answer» Right answer is (C) Low power dissipation The best I can explain: SINCE power dissipation in MOSFET is less, this results in smaller heat SINKS and thus the cost of the AMPLIFIER will be reduced.
