Abstract
Provided are analog-digital converting circuits including a comparator, and an image sensor. The analog-digital converting circuit include a counter and a comparator, the comparator including a first P-type transistor including a gate connected to a first input node of the comparator, a second P-type transistor including a gate connected to a second input node of the comparator, a first N-type transistor including a gate connected to the first input node and a drain connected to the first P-type transistor, a second N-type transistor including a gate connected to the second input node and a drain connected to the second P-type transistor, and a transistor including a gate connected to the drain of the first N-type transistor and a source to which ground voltage or power supply voltage is applied.
