Abstract
A circuit device includes a transfer gate, a charge compensation circuit, and a control circuit. The control circuit controls the charge compensation circuit. The charge compensation circuit discharges charge from an output node of the transfer gate when a voltage of an input signal to the transfer gate is in a first voltage range at a timing at which the transfer gate is turned off. The charge compensation circuit injects charge into the output node of the transfer gate when a voltage of the input signal to the transfer gate is in a second voltage range lower than that in the first voltage range at a timing at which the transfer gate is turned off.
