Abstract
The present invention provides an amplifying circuit capable of accomplishing high-impedance input/output, and providing a high gain and low power consumption. The amplifier amplifies a signal received through an input terminal, and outputs the signal through an output terminal. A control circuit comprised of the inductors, and the switches turns input/output impedances of the amplifier into a high impedance.
