Imaging systems including row-period compensators and associated methods
An imaging system includes an image sensor and a row-period compensator. The image sensor includes an array of photosensitive pixels and electrical circuitry for controlling the array of photosensitive pixels and for reading accumulated electrical charge therefrom. The electrical circuitry is at least partially powered from a positive power rail and a negative power rail. The row-period compensator is for compensating for a change in current drawn by the electrical circuitry during at least part of a row-period of the image sensor, and the row-period compensator is electrically coupled between the positive and negative power rails. A method for compensating for a change in current drawn by electrical circuitry of an image sensor includes controlling a magnitude of compensation current drawn by a row-period compensator, to compensate for a change in current drawn by the electrical circuitry of the image sensor.
