Abstract
An image sensor includes image sensor cells, each configured to generate an image signal in response to control signals. The image sensor also includes an ADC to receive the image signals of the image sensor cells, and a first driver to generate one or more first control signals for a first image sensor cell, where the first driver includes a first negative supply terminal. The image sensor also includes a first multiplexor to selectively connect the first negative supply terminal of the first driver to one of a plurality of power supply nodes, and a second driver to generate one or more second control signals for a second image sensor cell, where the second driver includes a second negative supply terminal. The image sensor also includes a second multiplexor to selectively connect the second negative supply terminal of the second driver to one of the power supply nodes.
