摘要： Disclosed are embodiments of a pixel imaging circuit that incorporates a standard photodiode. However, the imaging circuit is modified with a feedback loop to provide a first photo response over a first portion of the light sensing range (e.g., at higher light intensity range) and a second reduced-sensitivity photo response over a second portion of the light sensing range (i.e., at a lower light intensity range), thereby extending the circuits dynamic range of coverage. Also disclosed are embodiments of an associated imaging method and a design structure that is embodied in a machine readable medium and used in the imaging circuit design process.
