Abstract
An analog-to-digital convertor of an integration type, includes: a charging circuit having a capacitor configured to store electric charges based on an input current; a discharging circuit configured to discharge the electric charges stored in the capacitor; and a counting circuit configured to count a charge-discharge count of the capacitor in a first conversion period and in a second conversion period, in order to convert a current value of the input current into a digital value, wherein the first conversion period includes a first pre-charging period and a first counting period, the second conversion period includes a second pre-charging period and a second counting period, and the analog-to-digital convertor further comprises a phase changing circuit configured to change a first phase of an output signal of the charging circuit in the first counting period to a second phase in the second counting period.
