Abstract:
A charge transfer circuit has a charge transfer unit including an input charge holding element holding an input charge, an output charge holding element holding an output charge, and a charge transfer element, provided between a first node of the input charge holding element and a second, node of the output charge holding element, to transfer the charge held by the input charge holding element to the output charge holding element, an error sensing circuit detecting a third voltage corresponding to a first voltage of the first node when the charge transfer element finished transferring the charge from the input charge holding element to the output charge holding element, and an error correction unit correcting a second voltage of the second node when the charge transfer finished based on the third voltage and eliminate an error included in the second voltage of the second node.
