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.
