ABSTRACT:
A MOS power amplifier circuit comprised of a load driver including two p-channel MOSFETs connected in series, a preamplifier for amplifying an analog input signal and supplying the amplified one to the gate of one of the MOSFETs and for rendering the impedance of the two MOSFETs low; and an inverting amplifier for invert-amplifying the output signal from the preamplifier and supplying the amplified one to the gate of the other MOSFET. The operating voltage of the preamplifier and the inverting amplifier is higher than that of the load driver.
