Abstract
A method of an image sensor device includes: providing a pixel array having multiple bipolar junction transistor (BJT) pixel circuits arranged in N rows and M columns; and shortening a setting time period of a BJT sensing circuit in the pixel array during the setting time period by dynamically changing a bias current provided from a current source of the BJT sensing circuit during the setting time period.
