  • Publication number: 20190313045
    Abstract: 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.

  • Patent number: 10210442
    Abstract: An image forming system identifies a user's operation for changing a set value related to a processing of the image forming apparatus or the post-processing apparatus. When the set value is changed during a continuous output operation of the image forming system, the image forming system causes the image forming apparatus and the post-processing apparatus to continue the continuous output operation while reflecting the changed set value. The image forming system Detects a predetermined change related to the processing by referring back to a time when the user's operation is identified, and causes the image forming apparatus and the post-processing apparatus to re-output papers that have been output from a time when the predetermined change occurred to a time when the changed set value was reflected.
