  • Patent number: 9083368
    Abstract: An image sensor includes multiple counters and a counter controller. Each counter of the multiple counters is configured to perform counting of a comparison result signal and to generate a count result, the comparison result signal being obtained by comparing a ramp signal and a pixel signal of a column of multiple columns. The counter controller is configured to generate and transmit a counter clock signal and (n?1) delay clock signals to the counters, respectively, ā€œnā€ being a natural number equal to or greater than two. Each delay clock signal of the (n?1) delay clock signals is obtained by delaying the counter clock signal by a corresponding offset code.

    Abstract: An image sensor includes a pixel array, a plurality of comparators, a plurality of counters and a plurality of synchronization circuits. The pixel array includes a plurality of pixels configured to generate analog signals by sensing incident light. The comparators generate comparison signals by comparing the analog signals with a reference signal. The counters are grouped into a plurality of counter groups. Each of the counters generates digital signals corresponding to the analog signals by counting, the counting terminated by the comparison signals. Each of the synchronization circuits synchronizes input clock signals to a source clock signal to provide synchronized input clock signals to each of the counter groups.
