Patent number: 12273641Abstract: In a solid-state imaging element provided with a comparator for each column, responsiveness of the comparator is improved. An input transistor outputs, from a drain, a potential within a range from one side to the other side of a pair of output potentials on the basis of whether or not an input potential input to a source and a predetermined reference potential input to a gate substantially coincide with each other. A first current source supplies a constant current. A capacitor is inserted between the source of the input transistor and a first current source. A cutoff switch disconnects a drain of the input transistor from a connection node within a predetermined period for initializing the connection node between the capacitor and the first current source to a lower one of the pair of output potentials, and connects the connection node with the drain of the input transistor outside the predetermined period.Type: GrantFiled: June 25, 2021Date of Patent: April 8, 2025Assignee: SONY SEMICONDUCTOR SOLUTIONS CORPORATIONInventors: Daisuke Nakagawa, Takashi Moue, Yoshio Awatani
