ABSTRACT:
A charge transfer device is disclosed. The charge transfer device has: a charge transfer section for outputting a signal charge; a voltage signal output circuit for converting the signal charge into a voltage and outputting a voltage signal; a reference signal output circuit for outputting a reference signal of a predetermined voltage, the reference signal output circuit having a circuit constant substantially equal to a circuit constant of the voltage signal output circuit; and a differential operational amplifying circuit for amplifying a difference between the voltage signal from the voltage signal output circuit and the reference signal from the reference signal output circuit and outputting the amplified difference.
