Claim:
1. An imaging device comprising: a pixel configured to convert an incident light into a pixel signal; a signal line connected to the pixel to convey the pixel signal; an A/D converter configured to perform an analog to digital conversion, the A/D converter including a comparator; a switch circuitry disposed between the signal line and the comparator, the switch circuitry being configured to control a connection between the signal line and an input terminal of the comparator; maintenance circuitry disposed between the comparator and the switch circuit, the maintenance circuitry being configured to hold the pixel signal conveyed by the switch circuit; and a control unit configured to supply a control signal for controlling the switch circuit, wherein the maintenance circuitry includes a capacitor, the capacitor being coupled between a predetermined potential and the switch circuitry, wherein the switch circuitry includes a P-type transistor and an N-type transistor that is coupled in parallel with the P-type transistor, and a gate of the P-type transistor is coupled to the N-type transistor through an inverter.
