ABSTRACT:
A transistor amplifier comprised of a class-A amplifier connected in cascade with a push-pull amplifier. The class-A amplifier includes first and second field effect transistors having triode-type dynamic characteristics with their respective gate electrodes connected to receive an input signal and their source and drain electrodes connected in series across opposite power supply terminals. The push-pull amplifier includes third and fourth field effect transistors having triode-type dynamic characteristics with their respective gate electrodes connected to the first and second field effect transistors and their source and drain electrodes connected in series across the opposite power supply terminals.
