ABSTRACT:
A switching amplifier includes a grounded collector NPN Darlington amplifier having a main current path connected between a terminal for receiving an operating voltage and an output terminal, and an input base and output emitter electrodes across which a series circuit of the main conduction of an NPN transistor and a floating DC voltage supply are connected. In response to a switching signal applied to its base electrode, the NPN transistor turns on to connect in "bootstrap" the DC voltage supply directly across the base and emitter electrodes of the Darlington amplifier, for turning on and operating the Darlington amplifier at its maximum power and rated voltage or current capability.
