Abstract
A first output stage outputs current to an output terminal via current-mirror circuits based on a voltage difference input to non-inverting and inverting terminals. A second output stage comprises current providing transistors connected with the current-mirror circuits of the first output stage in a current-mirror manner for providing current, and outputs the current to the output terminal via rectifying components and switches.
