DAC circuit, solid-state imaging element, and electronic equipment
The present technology relates to a DAC circuit, a solid-state imaging element, and electronic equipment that can be achieved with a small-scale circuit configuration. The DAC circuit includes: a ramp DAC that generates a ramp signal that changes in voltage with a constant time gradient; an injection DAC that outputs a predetermined voltage during a reset period for resetting a comparison target voltage to be compared with the ramp signal; and an adding circuit that adds an output of the ramp DAC and an output of the injection DAC and outputs the outputs to a comparison circuit as a comparison reference voltage. The present technology can be applied to, for example, a DAC circuit of a solid-state imaging element, and the like.
