Power Amplifiers

  • Malcolm Goodge


  • Consideration of the most significant aspects of power amplifiers; power efficiency and distortion.

  • Classification of power stages according to mode of operation; classes A, B, AB, C, D and E.

  • Analysis of class A and class B stages leading to the popular class AB circuit.

  • Discussion of the operation and merits of class C, D and E stages.
