Limits to the Timing Performance of Single Photon Avalanche Diodes
1995Semiconductors p-n junctions with uniform breakdown voltage are gaining acceptance as single-photon detectors in the visible and near infrared wavelength range in many applications, such as measurements of fast optical signals, laser ranging, Optical TimeDomain Reflectometry and in all cases where fast andlor weak optical signals must be detected1,2 ...

Physics and numerical simulation of single photon avalanche diodes
IEEE Transactions on Electron Devices, 1997We present results of the numerical simulation of the transient behavior of shallow junction single photon avalanche diodes (SPAD's). We developed a bidimensional model for above breakdown simulations and show that the initially photogenerated charge density builds up locally by an avalanche multiplication process and then spreads over the entire ...

Improving the performance of silicon single-photon avalanche diodes
SPIE Proceedings, 2011Many applications require high performance Single Photon Avalanche Diodes (SPAD) either as single pixels or as small arrays of detectors. Although currently available silicon devices reached remarkable performance, nevertheless further improvements are needed in order to meet the requirements of most demanding time-resolved techniques. In this paper we

Single photon avalanche diode for single molecule detection
Review of Scientific Instruments, 1993A commercially available single photon avalanche photodiode in a passively quenched circuit is used with time-correlated single photon counting modules to achieve subnanosecond time response together with high quantum efficiency and low dark noise. These characteristics are required for experiments in single molecule detection and spectroscopy in which

Single photon avalanche diode for single molecule detection
Optical Society of America Annual Meeting, 1992Single dye molecules may be detected as they pass through a 0.4 pL sample volume by using repetitively pulsed laser excitation and time-gated single photon counting to detect the weak single-molecule fluorescence and simultaneously discriminate promptly scattered Raman photons arising from the >1013 solvent molecules.1 Previous experiments have ...

Monolithic quenching-and-reset circuit for single-photon avalanche diodes
2014 21st IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2014A novel quenching-and-reset circuit for single-photon avalanche diodes is presented. The circuit has been fabricated in a standard 0.6-um CMOS technology and can operate with detectors biased up to 5 V above breakdown. The circuit functionality has been verified by experimental measurements, showing a programmable hold-off time from 50 ns for reducing ...

Behavioral modeling of statistical phenomena of single‐photon avalanche diodes
International Journal of Circuit Theory and Applications, 2011SUMMARYIn this paper, we present an accurate behavioral model for simulating single‐photon avalanche diodes (SPADs). The device operation is described using the Verilog‐A description language, which is an analog extension of the common digital hardware description language.

An analysis of the information efficiency of single photon avalanche diodes
2012 IEEE 55th International Midwest Symposium on Circuits and Systems (MWSCAS), 2012In this work, we model single photon avalanche diodes (SPADs) as communication channels. We apply classical Shannon results for a Gaussian channel to typical SPAD circuits. Thus we look at the information rate and the bit energy of the circuit. By considering the noise sources for a generic SPAD sensor we develop the information rate model as a ...

Fast Gating of Single-Photon Avalanche Diodes for Photon Migration Measurements
2009Near-Infrared (NIR) picosecond pulsed light shined in biological tissues offers the opportunity for non-invasive imaging. We aimed at developing a winning photodetector electronics pairing for a broad field of multiple-wavelengths faint-signal optical investigations, like functional brain imaging.
