Abstract
The current feedback output circuit includes first and second transistors. The current feedback output circuit includes a current amplifier that has a non-inverting input terminal, an inverting input terminal, a first output terminal and a second output terminal, an input impedance of the non-inverting input terminal being higher than an input impedance of the inverting input terminal, and flows a current obtained by amplifying the difference between a current of an input signal to the non-inverting input terminal and a current input to the inverting input terminal between the first output terminal and the second output terminal. The current feedback output circuit includes first to sixth current mirror circuits. The current feedback output circuit includes a current feedback circuit that supplies a current responsive to a voltage at the signal output terminal to the inverting input terminal.
