Claim 0:
1. A solid-state imaging element comprising:
a first comparator that includes
a first input transistor that outputs, from a drain of the first input transistor, a first voltage corresponding to an input voltage received from a first pixel, in reference to a first voltage difference between the input voltage input to a source of the first input transistor and a first reference voltage input to a gate of the first input transistor, and
a first output transistor that outputs, from a drain of the first output transistor, a comparison result of comparison between the input voltage and the first reference voltage in reference to a second voltage difference between the input voltage input to a source of the first output transistor and the first voltage input to a gate of the first output transistor; and

a second comparator that includes
a second input transistor that outputs, from a drain of the second input transistor, a second voltage corresponding to the input voltage in reference to a third voltage difference between the input voltage input to a source of the second input transistor and a second reference voltage input to a gate of the second input transistor, and
a second output transistor that outputs, from a drain of the second output transistor, a comparison result of comparison between the input voltage and the second reference voltage in reference to a fourth voltage difference between the input voltage input to a source of the second output transistor and the second voltage input to a gate of the second output transistor.
