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.

Electronic device including monitoring circuit of ramp signal and operating method thereof

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.
