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.

According to a recent European Union report, lighting represents a significant share of electricity costs and the goal of reducing lighting power consumption by 20% demands the coupling of light-emitting diode (LED) lights with smart sensors and communicat ...

This paper deals with 24-GHz circuits developed by exploiting a system-in-package approach. In order to reduce the cost as much as possible, a standard multilayer printed circuit board (PCB) technology has been adopted. Such a circuit consists of a package ...

This paper presents a microwave noise source implemented in a commercial CMOS technology. The circuit is based on the avalanche noise generated by both the source-to-bulk and the drain-to-bulk junctions in reverse breakdown. Two sources of different juncti ...

With the rapid development of the applications in short range communication, phased-array receiver working at 24 GHz can provide enhanced gain performance at desired transmission direction. Also there is the wide signal bandwidth, i.e. 250 MHz free license ...

A 4 th order Gm-C elliptic low-pass filter with a wide continuous tuning range is presented. The continuous tuning is achieved by means of a new tuning circuit which adjusts the bias current of the Gm cell's input stage to control the cut-off frequency. Wi ...

This paper proposes, for the first time, a compact model for avalanche noise diodes that can easily be inserted in advanced CAD tools. The model is based on the theory of the Read type microwave avalanche diodes. It fully accounts for the electronic tuning ...

This paper presents a design methodology for high quality factor resonators based on operational transconductance amplifier (OTA) employed in active filters. The quality factor of a resonator, as its main specification, is translated to the requirements of ...

Next generation of smart tires will improve the safety and stability of the vehicle by monitoring road parameters, such as pavement and rolling conditions, with sensors placed on tire surface. Between the tread and the metal belt of the tire there are only ...

We propose an autonomous battery-less wireless sensor node that combines on a single printed circuit board an ultra-wideband (UWB) transmitter and its printed antenna, together with a piezoelectric cantilever and a solar cell array to harvest vibrations an ...

We explore a miniature sensor node that could be placed in an environment which would interrogate, take decisions and transmit autonomously and seamlessly without the need of a battery. With the system completely powered by an energy harvester for autonomo ...

This paper presents a design methodology for common-mode (CM) stability of operational transconductance ampliﬁer (OTA)-based gyrators. The topology of gm−C active inductors is brieﬂy reviewed. Subsequently, a comprehensive mathematical analysis on the CM s ...

This paper deals with the design of a 4-channel phased-array receiver Front-End (FE) architecture working at 24 GHz. Targeting low power applications such as radar sensors and medium bit-rate transceivers, a local oscillator shifting architecture is propos ...
