The present disclosure relates to a comparator, an AD converter, a solid-state imaging device, an electronic apparatus, and a comparator control method that can reduce power consumption while increasing the determination speed of the comparator. The comparator includes a comparison unit, a positive feedback circuit, and a current limiting unit. The comparison unit compares the voltage of an input signal and the voltage of a reference signal, and outputs a comparison result signal. The positive feedback circuit increases the transition speed at the time when the comparison result signal is inverted. The current limiting unit limits the current flowing in the comparison unit after the inversion of the comparison result signal. The present disclosure can be applied to comparators, for example.

A color imaging element, a photosensor and a photoelectric transducer which use a protein and are capable of being stably used for a long time, and methods of manufacturing them are provided. A zinc-substituted cytochrome c552 is immobilized on a gold electrode with a self-assembled monolayer in between to form a blue-light photoelectric transducer. Alternatively, a cytochrome c552 is immobilized on a gold electrode with a self-assembled monolayer in between, and a fluorescent protein absorbing blue light is bonded to the cytochrome c552, thereby forming a blue-light photoelectric transducer. These photoelectric transducers each are used as a color imaging element or a blue-light photoelectric transducer of a photosensor.
