  • Image sensor, image processing system including the same, and operating method of the same
    Patent number: 11528439
    Abstract: An image sensor includes a dual conversion gain pixel to output a high conversion gain signal according to a high conversion gain and output a low conversion gain signal according to a low conversion gain, by adjusting a conversion gain; a scaler to scale a voltage level of the high conversion gain signal; a ramp generator to generate a first ramp signal and a second ramp signal, slopes of the first and second ramp signals being different from each other; a comparator to compare the scaled high conversion gain signal and the first ramp signal to output a first comparison result, and compare the low conversion gain signal and the second ramp signal to output a second comparison result; and a counter to output a first counting result value based on the first comparison result and output a second counting result value based on the second comparison result.

  • ELECTRONIC DEVICE INCLUDING MONITORING CIRCUIT OF RAMP SIGNAL AND OPERATING METHOD THEREOF
    Publication number: 20220266845
    Abstract: An electronic device includes a ramp generator configured to generate a ramp signal used to detect data, the ramp signal increasing or decreasing with a certain slope; a main circuit configured to perform at least one predefined function by detecting the data based on the ramp signal; a monitoring circuit configured to output a verify signal indicating whether the ramp signal is faulty; and a controller configured to control execution of the at least one predefined function based on the verify signal.
