Abstract: An image sensor includes a pixel array including a plurality of pixel groups arranged in a plurality of rows and columns, the plurality of pixel groups configured to convert a light into electrical signals and to generate pixel signals, a row driver configured to generate a plurality of control signals for controlling the rows of the pixel array, and one or more power management devices configured to generate a power supply voltage for generating the plurality of control signals based on an input signal, and supply the power supply voltage to the row driver. Each of the one or more power management devices includes a first chopping circuit configured to modulate the input signal, an amplifier configured to generate an output signal based on the modulated input signal, and a second chopping circuit configured to demodulate the output signal and to modulate a noise caused by the amplifier.

Abstract: An image sensor includes a pixel array connected to a plurality of column lines, a first ramp signal generator generating a first ramp signal, a second ramp signal generator generating a second ramp signal, and an analog-to-digital conversion (ADC) circuit operating in a first mode. The ADC circuit includes a first comparator group comparing the first ramp signal with a first pixel signal received from a first column line group, among the plurality of column lines, and a second comparator group comparing the second ramp signal with a second pixel signal received from a second column line group, among the plurality of column lines. The comparing of the first ramp signal occurs at a comparison time point different from a comparison time point during which the comparing of the second ramp signal occurs.
