Abstract
A multimode pixel of a pixel array is provided. The multimode pixel includes a photodetector, an image sensing circuit having a first plurality of transistors, and a laser range finding (LRF) circuit having a second plurality of transistors. At least one transistor of the second plurality of transistors, but not all of the second plurality of transistors, is included in the first plurality of transistors. The LRF circuit being configured to perform LRF operations and the image sensing circuit is configured to perform passive imaging operations. The image sensing circuit and the LRF circuit are configured to perform concurrently.
