APD and SPAD Receivers : Invited Paper

2019 15th International Conference on Telecommunications (ConTEL), 2019
Integrated receivers with avalanche photodiodes (APDs) and single-photon avalanche diodes (SPADs) fabricated in 0.35μm CMOS and BiCMOS technologies are introduced. The APD receivers were used in error-free optical wireless communication (OWC) experiments with maximum transmission distances from 11m to 27m at 1Gb/s and from 6.5m to 16.5m at 2Gb/s ...

SPAD based image sensors

2014 IEEE International Electron Devices Meeting, 2014
The recent availability of miniaturized photon-counting pixels in standard CMOS processes has paved the way to the introduction of photon counting in low-cost time-of-flight cameras, robotics vision, mobile phones, and consumer electronics. In this paper we describe the technology at the core of this revolution: single-photon avalanche diodes (SPADs ...
