Power Amplifiers Introduction to Power Amplifiers Power Amplifiers • Crossover distortion. Amplifier circuits form the basis of most electronic systems, many of which need to produce high power to drive some output device. Audio amplifier output power may be a nything from less than 1 Watt to several hundred Watts. Radio frequency amplifiers

B or -C amplifiers using the same transistor at the same frequency and output power. For example, a Class-B or -C power stage operating at 65% collector or drain efficiency (losses = 35% of input power) would have an efficiency of about 85% (losses = 15% of input power) if changed to Class E (35%/15% = 2.3). Class-E amplifiers can be
