Abstract
Various technologies described herein pertain to automatically adjusting the strength of a voltage booster of an image sensor. A self-scaled voltage booster includes a regulator, a controller, and two or more charge pumps that can be selectively enabled and disabled by the controller. The controller generates controller signals for the charge pumps based on a duty cycle of a regulator signal generated by the regulator. Moreover, the controller can maintain the controller signals without modification for at least a predetermined minimum period of time after a prior modification of at least one of the controller signals. Further, the controller can include a duty cycle and delay module (or a plurality of duty cycle and delay modules) that detects the duty cycle of the regulator signal and maintains the controller signals without modification for at least the predetermined minimum period of time.
