Abstract
A driver circuit is improved in drive capability corresponding to a resolution increase for a CCD sensor while suppressing chip size of a driver circuit. A preceding-stage circuit, operating on V(>V) and V2 (<V), is provided in a stage preceding an output-stage circuit operating on Vand V. The output-stage has a transistor QPd that turns on when supplied with a gate voltage Vfrom the preceding-stage circuit, thus outputting, onto an output terminal Vout, a voltage Vand a current according to a voltage Vgs (=V−V). In addition, a transistor QNd turns on when supplied with a gate voltage Vfrom the preceding-stage circuit, thus outputting, onto an output terminal Vout, a voltage Vand a current according to a voltage Vgs (=V−V). Because these Vgs are greater than V−V, the output-stage circuit can be improved in drive capability and transistor size be correspondingly suppressed.
