Abstract
An image sensor with an active pixel array and peripheral dummy pixels is disclosed. The dummy pixels are located between (a) at least a portion of the active pixel array and (b) undesired or potentially interfering noise from a noise source. Outputs of the dummy pixels are coupled to float with respect to the active pixel array, thereby blocking the noise from being coupled into the active pixel array.
