Abstract
The present disclosure relates to a sensor element and an electronic device that can further reduce noise. In a solid-state imaging apparatus that performs AD conversion in a pixel, a comparator circuit included in the pixel at least has: a comparing unit that compares a pixel signal output from a pixel circuit with a reference signal which is a slope signal whose level monotonously decreases with time; a band limiting unit that performs band limiting by narrowing a band of a signal that changes according to a result of comparison by the comparing unit; and an amplification unit that amplifies the signal whose band has been limited through the band limiting unit. The present technology can be applied to a solid-state imaging apparatus that performs AD conversion in a pixel, for example.
