Abstract

See full text

A system that has plural different photodetector circuits, each photodetector circuit including its own transfer gate, and each of the plural different photodetector circuits and transfer gates commonly connected to a first node. In amplifier is used which maintains a fixed voltage edits input. The amplifier Has a first capacitance to ground in a second capacitance as a feedback between its output and input. In one embodiment, there are 16 photodetector circuits connected to the single amplifier. In embodiments, the photodetector circuits can be located in one substrate while the amplifier is located in another substrate, and the amplifier also minimizes parasitics between the substrates.
