Abstract:
1. A charge transfer circuit comprising: a charge transfer unit including an input charge holding element that is configured to hold an input charge, an output charge holding element that is configured to hold an output charge, and a charge transfer element that is provided between a first node of the input charge holding element and a second node of the output charge holding element and is configured to transfer the charge held by the input charge holding element to the output charge holding element; an error sensing circuit being configured to detect 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 being configured to correct 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.
