Abstract
An image sensor may have a power supply voltage regulator controlled by a feedback loop. The feedback signal may be derived by applying the supply voltage at a point distant from the voltage regulator to an analog-to-digital converter (ADC) which may be a spare channel of an ADC provided for the output of the pixel array. The digital feedback loop may be controlled via a chip IC bus.
