  • Patent number: 12273641
    Abstract: 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.

  • Patent number: 12177591
    Abstract: A degree of freedom in design is improved in a solid-state imaging element in which a logic gate is provided in a comparator. A comparison circuit compares an input potential which has been input with a predetermined reference potential and outputs any one of a pair of output potentials as a comparison result. A level shift circuit outputs any one of a pair of shift potentials having a larger potential difference than the pair of output potentials as an output signal on the basis of the comparison result. The logic gate determines whether or not the output signal is higher than a predetermined threshold between the pair of shift potentials and outputs a determination result. A counter counts a count value over a period until the determination result is inverted.

  • Publication number: 20230412942
    Abstract: The technology of the present disclosure improves an image quality in a solid-state imaging element that amplifies a voltage for every column. In the solid-state imaging element, an input transistor outputs, from a drain, an output voltage corresponding to a voltage between a source and a gate to which an input voltage is input. A base side current source transistor supplies a predetermined current from the drain of the input transistor to a base node determined in advance. A feedback circuit feeds back a part of the predetermined current to the gate of the input transistor. The clamp circuit limits the output voltage to a value higher than a lower limit voltage determined in advance.

  • Patent number: 11746891
    Abstract: In a shift lever device, a lock bar is disposed in a restricting position to restrict changing of a shift position of a lever. A motor is driven to rotate a cam in order to move the lock bar to a non-restricting position, thereby permitting changing of the shift position of the lever. The lock bar is moved as the rotation position of the cam is changed. This enables the precision required of the rotation position of the cam in order to dispose the lock bar in the restricting position and the non-restricting position to be lowered, thereby enabling appropriate switching between restriction and permission of changes in shift position of the lever to be performed by driving of the motor.
