Integrating analog-to-digital converter and semiconductor device

An integrating analog-to-digital converter comprising:

• a global counter outputting a counter code signal including a multiphase signal;
• a column circuit including:
• a ramp wave generation circuit outputting a ramp wave voltage whose voltage value changes linearly according to time change;
• a comparator comparing the ramp wave voltage with a pixel voltage generated by a pixel;
• and
• a latch circuit latching the counter code signal at timing at which an output of the comparator is inverted;
• an output value of the latch circuit being converted into a digital conversion output value per the column circuit;
• and
• a phase division circuit inputting the counter code signal, generating a phase division signal that divides a phase of the counter code signal, and outputting the phase division signal to the latch circuit as an LSB of the digital conversion output value of the integrating analog-to-digital converter,
• wherein the global counter is shared to a predetermined number of the column circuit, and
• wherein the phase division circuit is arranged for a plurality of column circuits composed of the column circuit, the number of column circuits being a number smaller than the predetermined number, and the LSB is shared by a plurality of phase division circuits composed of the phase division circuit.
