Abstract—Timing jitter is one of the most important characteristics of single-photon avalanche diodes (SPADs), especially in applications requiring accurate photon timing, such as timecorrelated single photon counting (TCSPC) or LiDAR. In this article, we describe a measurement setup for the characterization of the timing jitter of actively-quenched SPADs using the TCSPC technique with a picosecond laser. By also describing the typical mistakes and potential pitfalls with such a setup, we aim to give a useful guideline on reproducing a setup with well-defined measurement uncertainty, in order to achieve comparable results
between devices of different manufacturers, both academic and commercial. In addition, we describe the physical cause of the jitter in SPADs to aid designers in the design of a new generation of low-jitter SPAD devices.

Be aware of the avalanche! Learn how an avalanche photodiode (APD) works and see which devices X-FAB is offering for integration in its modular high voltage XH018 process.
Everybody is talking about single photon avalanche diodes (SPAD) for LiDAR and Time-of-Flight. Do you know what is required to upgrade from an APD to a SPAD? How can a good active quenching circuit be designed?
The webinar will introduce newly-developed APD and SPAD devices. You will be provided with information about the key parameters and learn how to integrate them into X-FAB’s process. X-FAB is offering a reference circuit for active quenching: discover how it works and how it could reduce your time for design.
Even though image sensors have become smaller and smaller in the past years for usage in mobile phone and digital cameras, there are still applications which require large image sensors. For example, X-Ray sensors are used in a wide range of medical, industrial and scientific applications. Such large pixel designs come with their specific design challenges especially if they have to been read out fast.
In this webinar X-FAB will showcase its 0.18 µm CMOS process (XS018) that is particularly well-suited for image sensors. The presentation will focus on large pixel designs. Several pixel layouts with different photodiode shapes have been tested and characterized. You will learn about the pros and cons with regards to speed, full well capacity and image lag for the these layout structures. Register now to find out how your pixel design can be optimized!
Micro-Electro-Mechanical-Systems (MEMS) are bridging as sensors and actuators the gap between the real analogue word and the digital world with their enormous data processing and data storage possibilities. MEMS solutions are providing significant advantages: small form factors allow the integration of sensors in miniaturized systems and their manufacturing in modern wafer processes makes them available in very high amounts at quite low costs.
Spectral sensors have been attracting increasing interest for years. Solutions available today are limited in terms of space requirements, costs and/or robustness (automotive qualification) in a way that many application scenarios cannot be addressed well.
Today’s emerging technologies like photovoltaics, smart grid and electromobility are operating at high voltages which are interesting to be sensed on-chip for further processing.
LEDs for luminaires:
- low cost and high efficiency
- dynamic (spectral) lighting
Sensor interfacing is a crucial component for today’s systems in many application domains. Especially in automotive and manufacturing fields, high temperatures are encountered. For extracting the typically small sensor signals, an interface near the sensor is needed to provide a high-accuracy and robustness.
X-FAB platforms provide a complete choice of design libraries, design tools and primitive devices supporting ULP/ULL solutions both at elementary and at sub-system level, for best-in-class power management.
