Optically-Clocked Instruction Set Extensions for High Efficiency Embedded Processors

Claudio Favi, Edoardo Charbon, Ties Jan Henderikus Kluter, Christian Mester

We propose a technique to localize computation in Instruction Set Extensions (ISEs) that are clocked at very high speed with respect to the processor. In order to save power, data to and from Custom Instruction Units (CIUs) is synchronized via an optical s ...

3D Near-infrared Imaging based on a Single-photon Avalanche Diode Array Sensor

Claudio Favi, Cristiano Niclass, Edoardo Charbon, Juan Mata Pavia, Matthias Wolf

A new imager for 3D near-infrared imaging has been designed based on a single-photon avalanche diode (SPAD) imager with 128x128 pixels capable of performing time-resolved measurements with a resolution of 97ps. The imager linearity has been improved to mak ...

Single-Photon Techniques for Standard CMOS Digital ICs

Claudio Favi

The advent of single-photon detectors known as Single-Photon Avalanche Diodes in standard CMOS technology opened the way to new perspectives in integrating these ultra sensitive light sensors with digital logic. Light has some interesting properties that a ...

A 17 ps Resolution, Temperature Compensated Time-to-Digital Converter in FPGA Technology

Claudio Favi, Edoardo Charbon

A time-to-digital converter (TDC) architecture is presented enabling a time resolution of 17 ps over 50 ns and achieving twenty million conversions per second. The TDC, designed in a 65nm FPGA, is implemented as a pipelined interpolating architecture; it c ...

Single-Photon Synchronous Detection

Claudio Favi, Cristiano Niclass, Edoardo Charbon, Frédéric Monnier, Ties Jan Henderikus Kluter

Phase and intensity of light are detected simultaneously using a fully digital imaging technique: single-photon synchronous detection. This approach has been theoretically and experimentally investigated in this paper. We designed a fully integrated camera ...

Single-Photon Synchronous Detection

Claudio Favi, Cristiano Niclass, Edoardo Charbon, Frédéric Monnier, Ties Jan Henderikus Kluter

A novel imaging technique is proposed for fully digital detection of phase and intensity of light. A fully integrated camera implementing the new technique was fabricated in a 0.35μm CMOS technology. When coupled to a modulated light source, the camera can ...

Techniques for Fully Integrated Intra-/Inter-chip Optical Communication

Claudio Favi, Edoardo Charbon

In this paper we propose to eliminate all data and control pads generally present in conventional chips and to replace them with a new type of ultra-compact, low power optical interconnect implemented almost entirely in CMOS. The proposed scheme enables en ...
