ABSTRACT:
The same input signal is applied to each of the bases of a pair of amplifying transistors, while an output signal is produced at the emitter of one of the pair of transistors. The collector of the one transistor is connected to the emitter of the other transistor. The junction point between the collector of the one transistor and the emitter of the other transistor is connected through a diode to a first DC power source of low voltage. A second power source of high voltage is connected to the collector of the other transistor, thereby selectively supplying electric power to the one transistor in accordance with the signal level of the input signal. An inductance element is connected in series with the diode to generate a counter electromotive force to prevent a reverse current from flowing through the diode during the cut-off state of the diode, thus providing a highly efficient amplifier with little distortion.
