Abstract
Provided herein is a novel pixel circuit for image sensors such as IR ROIC image sensors. The design provides a switchable pixel with two modes. In the first mode, the pixel performs in-pixel correlated double sampling to remove reset noise. In the second mode, the pixel is configured in a high-capacity mode to avoid saturation. The pixel may be dynamically switched between modes, for example in response to lighting conditions in the scene to be imaged.
