Abstract
Disclosed is a video signal output circuit including: a clamp circuit; a first differential amplifying circuit; a dividing circuit; and an offset circuit which adds or subtracts a predetermined offset voltage to or from a bias voltage, a reference voltage, or a base reference voltage generated by the dividing circuit so as to supply an offset voltage added/subtracted voltage to the clamp circuit or the first differential amplifying circuit, wherein the offset circuit includes a pnp bipolar transistor and an npn bipolar transistor, and outputs a difference voltage corresponding to a difference between a base-emitter voltage of the pnp bipolar transistor and a base-emitter voltage of the npn bipolar transistor.
