ABSTRACT:
The invention is directed to an improved electronic circuit using MOSFET (FET) devices for use in a first embodiment as a class D amplifier and in a second embodiment as a voltage balance circuit for a class D amplifier. In the first embodiment the operating functions of a conventional class D MOSFET amplifier is improved by the addition of a pair of Schottky diodes one of which is connected between the source terminals of the FETs and another connected between the drain terminals of the FETs and the addition of a pair of inductors one connected between the source of one FET and a third inductor and the other connected from the drain of the other FET to the third inductor. The other side of the third inductor provides the output of the class D amplifier. In the second embodiment, the circuit of the first embodiment is converted to a voltage balance circuit by grounding the output end of the first two inductors.
