SPAD Developed in 55 nm Bipolar-CMOS-DMOS Technology Achieving Near 90% Peak PDP
Edoardo Charbon, Claudio Bruschini, Ekin Kizilkan, Pouyan Keshavarzian, Won Yong Ha, Francesco Gramuglia, Myung Jae Lee
We present a single-photon avalanche diode (SPAD) developed in 55 nm bipolar-CMOS-DMOS (BCD) technology, which achieves high photon detection probability (PDP) while its breakdown voltage is lower than 20 V. To enhance the PDP performance, the SPAD junctio ...
Ieee-Inst Electrical Electronics Engineers Inc2024A 73% Peak PDP Single-Photon Avalanche Diode Implemented in 110 nm CIS Technology With Doping Compensation
Edoardo Charbon, Claudio Bruschini, Ekin Kizilkan, Utku Karaca, Myung Jae Lee
In this article, we present 10 mu m diameter SPADs fabricated in 110 nm CIS technology based on an N (+) /HVPW junction, with enhanced sensitivity at short wavelengths. To reduce tunneling noise due to the highly-doped layers in the process, a doping compe ...
Ieee-Inst Electrical Electronics Engineers Inc2024Guard-Ring-Free InGaAs/InP Single-Photon Avalanche Diode Based on a Novel One-Step Zn-Diffusion Technique
Edoardo Charbon, Claudio Bruschini, Ekin Kizilkan, Utku Karaca, Vladimir Pesic, Myung Jae Lee
This work presents a novel InGaAs/InP SPAD structure fabricated using a selective area growth (SAG) method. The surface topography of the selectively grown film deposited within the 70 mu m diffusion apertures is used to engineer the Zn diffusion profile t ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Graph Representation Learning with Optimal Transport: Analysis and Applications
In several machine learning settings, the data of interest are well described by graphs. Examples include data pertaining to transportation networks or social networks. Further, biological data, such as proteins or molecules, lend themselves well to graph- ...
EPFL2022MATHICSE Technical Report: THU-Splines - Highly Localized Refinement on Smooth Unstructured Splines
We present a novel method named truncated hierarchical unstructured splines (THU-splines) that supports both local h-refinement and unstructured quadrilateral meshes. In a THU-spline construction, an unstructured quadrilateral mesh is taken as the input co ...
MATHICSE2021Engineering Breakdown Probability Profile for PDP and DCR Optimization in a SPAD Fabricated in a Standard 55nm BCD Process
Edoardo Charbon, Claudio Bruschini, Ekin Kizilkan, Pouyan Keshavarzian, Francesco Gramuglia, Myung Jae Lee
CMOS Single-Photon Avalanche Diodes (SPADs) have broken into the mainstream by enabling the adoption of imaging, timing, and security technologies in a variety of applications within the consumer, medical and industrial domains. The continued scaling of te ...
2021A Low-noise CMOS SPAD Pixel with 12.1 ps SPTR and 3 ns Dead Time
Edoardo Charbon, Claudio Bruschini, Ming-Lo Wu, Francesco Gramuglia, Myung Jae Lee
In this paper, we present the first CMOS SPAD with performance comparable or better than that of the best custom SPADs, to date. The SPAD-based design, fully integrated in 180 nm CMOS technology, achieves a peak PDP of 55% at 480nm with a very broad spectr ...
2021Self-Binarizing Networks
Sabine Süsstrunk, Radhakrishna Achanta, Fayez Lahoud, Pablo Marquez Neila
We present a method to train self-binarizing neural networks, that is, networks that evolve their weights and activations during training to become binary. To obtain similar binary networks, existing methods rely on the sign activation function. This funct ...
