Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Ballistic spin-filter transistor

Dirk Grundler

Spin-dependent ballistic transport in a mesoscopic two-dimensional electron system with two metallic ferromagnetic electrodes is studied using the Landauer-Büttiker formalism. Our calculations predict a pronounced spin-valve effect in the ballistic regime ...

Automatic design tool for submicron current steering logic libraries

Maher Kayal

Standard static CMOS logic is responding to the requirement of high frequency and low power of digital systems. However, the digital switching noise generated by this logic is not suited for the design of performance mixed-signal integrated systems. In mix ...

Optical logic gates by nonlinear mixing in BBO

Demetri Psaltis

An experimental demonstration of a set of optical logic gates (OR, XOR, AND) is shown using non-linear mixing in a BBO crystal. Pulses generated by a femtosecond Ti:Sapphire laser at 800 nm (140 fs duration, 2nJ/pulse) are split in 4 beams evenly separated ...

Single- and multi-wall carbon nanotube field-effect transistors

Herbert Shea

We fabricated field-effect transistors based on individual single- and multi-wall carbon nanotubes and analyzed their performance. Transport through the nanotubes is dominated by holes and, at room temperature, it appears to be diffusive rather than ballis ...

CMOS Current Steering Logic: Toward a matured technique for mixed-mode applications

Maher Kayal, Michel Declercq

This paper presents a detailed analysis of the CMOS Current Steering Logic (CSL) technique and compares experimentally its digital switching noise to that of the CMOS static logic. Theoretical analysis of the CSL inverter is developed. More complex gates u ...

Field Programmable Gate Array (FPGA) Circuits

Eduardo Sanchez

Field programmable gate arrays (FPGA) are a recently developed family of programmable circuits. Like mask programmable gate arrays (MPGA), FPGAs implement thousands of logic gates. But, unlike MPGAs, a user can program an FPGA design as traditional program ...

An aid in the teaching of multilevel inverters for high power applications

Alfred Rufer

Multilevel inverters represent a high potential for realization of a high power controllable conversion system of different nature, rectifiers, inveters, high power amplifiers, etc. From the even more applied three-level inverter to the multiple AC stages ...

Fabrication of 0.1 μm metal oxide semiconductor field-effect transistors with the atomic force microscope

Using the atomic force microscope (AFM), we have fabricated a metal oxide semiconductor field-effect transistor (MOSFET) on silicon with an effective channel length of 0.1 um. The lithography at the gate level was performed with the scanning tip of the AFM ...

All-Optical Reflectivity Tuning and Logic Gating in a GaAs/AlAs Periodic Layered Structure

Marc-André Dupertuis, Denis Martin

The optical nonlinearity of a GaAs/AlAs periodic layered structure was experimentally investigated for the first time. The shift of the reflectivity peak with increasing intensity was observed. A reflectivity contrast of about 10:1 was obtained by varying ...
