Abstract

An amplifier circuit for supplying output voltages which are much higher than the breakdown voltage of the individual components forming the amplifier comprises a control circuit (1) and an amplifier stage (2). The amplifier stage (2) comprises 2n transistors (7-12) where n is an integer greater than one, having their main current paths serially connected between two supply terminals (3, 4). The bases of the transistors (7-12) are connected to tapping points on a series chain of diodes (34-41) in the control circuit (1). Further supply sources (13-16) apply an incrementally decreasing sequence of voltages to transistors (8, 9) and (10, 11) so that the voltage across any of the transistors (7-12) is limited to one increment of the sequence of voltages.
