A 130nm CMOS Single Photon Avalanche Diode
We report on the first implementation of a single photon avalanche diode (SPAD) in 130nm CMOS technology. The SPAD is fabricated as p+/nwell junction with octagonal shape. A guard ring of p-well around the p+ anode is used to prevent premature discharge. To investigate the dynamics of the new device, both active and passive quenching methods have been used. Single photon detection is achieved b...
متن کاملSingle photon avalanche diode for single molecule detection
A 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 time-gated detection schemes are used. By ...
متن کاملPerformance trade-offs in single-photon avalanche diode miniaturization.
Single-photon avalanche diodes (SPADs) provide photons' time of arrival for various applications. In recent years, attempts have been made to miniaturize SPADs in order to facilitate large-array integration and in order to reduce the dead time of the device. We investigate the benefits and drawbacks of device miniaturization by characterizing a new fast SPAD in a commercial 0.18 microm compleme...
متن کاملElectrical μ-Lens Synthesis Using Dual-Junction Single-Photon Avalanche Diode
This work presents a dual-junction, single-photon avalanche diode (SPAD) with electrical μ-lens designed and simulated in 90 nm standard complementary metal oxide semiconductor (CMOS) technology. The evaluated structure can collect the photons impinging beneath the pixel guard ring, as well as the pixel active area. The fill factor of the SPAD increases from 12.5% to 42% in comparison with simi...
متن کاملDynamic Quenching for Single Photon Avalanche Diode Arrays
We propose the use of dynamic circuits for quenching avalanche events in single photon avalanche diode (SPAD) arrays. Two area-efficient, circuit solutions are presented in 0.35μm CMOS technology. These circuits contain no passive elements and consume shoot-through current only at triggering instants. The resulting reduction in power consumption and supply noise is essential to formation of lar...
