ABSTRACT:
A MOS-type FET (field effect transistor) amplifier includes a pair of P-channel and N-channel output stage MOS-type FETs which are ON-OFF controlled by a pulse signal and an inductive load. Each reverse current caused by the inductive load is shunted by a diode connected between the drain and source of each of the MOS-type FETs. An additional pair of diodes are provided in the drain-source circuits of the MOS-type FETs so as to prevent each reverse current flowing through respective substrates of the MOS-type FETs.
