Claim 2:
3. The image sensor of claim 1, wherein each of the first amplifier and the third amplifier comprises:
a first output transistor connected to a power supply terminal and a comparison node and having a gate connected to the comparison node;
a second output transistor connected to the power supply terminal and an output node and having a gate connected to the comparison node;
a first input transistor connected to the comparison node and a first bias node and having a gate connected to a second input node;
a second input transistor connected to the output node and the first bias node and having a gate connected to a first input node; and
