Abstract
An image sensor and a method of operating an image sensor to achieve a substantially uniform power signature. An array of pixels may be scanned using analog sensing circuitry to obtain an analog sensor output. The scanning is performed over a first time interval. The analog sensor output is converted to a digital data output using digital logic circuitry. The converting occurs over a second time interval that is subsequent to the first time interval and may be substantially the same duration as the first time interval. While the array of pixels are being scanned, the digital logic circuitry is operated over the first time interval and substantially coincides with the scanning of the array of pixels.
