Offering Students a Selection of Multiple Class B/AB Power Amplifiers as a Remote Laboratory

Abstract

In this paper a remote laboratory setup for conducting experiments on a class B/AB power amplifier is presented, addressing the problems related to running experiments requiring temperature matching between transistors and bias diodes, in order to avoid thermal runaway in the transistors. In addition there is an option for the student to quickly examine a range of different transistors in both class B and class AB setups.
