ABSTRACT:
A signal output circuit is used for an IC-patterned image sensor, including, at its signal processing part, source-follower amplifiers for converting a high impedance image signal to a low impedance image signal. To eliminate offset voltages of the amplifiers, an amplifier for converting the impedance of the image signal is disposed in parallel to an amplifier for converting an impedance of a reference voltage. A differential amplifier is used to calculate a difference between the foregoing two amplifiers. The signal output circuit includes a trimming circuit to adjust an offset voltage of these amplifiers.
