ABSTRACT:
A pixel for detecting at least a portion of the electromagnetic spectrum may be provided. The pixel includes a detector element for detecting at least a portion of the electromagnetic spectrum, a bias point coupled to an output of the detector element for applying a biasing voltage to the detector element and capable of affecting the electrical output of the first detector element, an interface-trap charge pump coupled to the output of the bias point for charge pumping current from the detector, a collection point coupled to the output of the bias point for accumulating an electrical output of the detector element, and an output point for providing an electrical output of the pixel.
