Abstract
An electronic device includes a shared epitaxial structure, an array of photodiodes formed in the shared epitaxial structure, and a readout circuit. The array of photodiodes is disposed between a first axis and a second axis, with the second axis orthogonal to the first axis. The array of photodiodes has an absence of guard structures between adjacent photodiodes. The readout circuit is electrically connected to the array of photodiodes and operable to read out values for different photodiodes or different subsets of photodiodes in the array of photodiodes.
