Abstract
A reference pixel sensor cell (e.g., global shutter) with hold node for leakage cancellation, methods of manufacture and design structure is provided. A pixel array includes one or more reference pixel sensor cells dispersed locally throughout active light sensing regions. The one or more reference pixel sensor cells provides a reference signal used to correct for photon generated leakage signals which vary by locality within the active light sensing regions.
