Abstract
Designs of an anti-blooming sensing element or simply sensor are described. According to one aspect of the designs, each sensing element includes a photosensor, a pair of first and second circuits, a store device and a readout circuit. The first and second circuits, sandwiching the photosensor from a circuit perspective, are mirrored and balanced in impedance. The first circuit provides an inherent mechanism to discharge excessive charge accumulated on the photosensor before a predefined exposure time ends. Each of the two circuits includes two transistors.
