RF MEMS power sensors for ultra-low power wake-up circuit applications

Mihai Adrian Ionescu, Catherine Dehollain, Montserrat Fernandez-Bolanos Badia, Antonios Bazigos, Wolfgang Amadeus Vitale

Power savings requirements in wake-up circuits and RFID applications can greatly benefit from the emerging RF MEM technology. In this paper we report an RF MEM power sensor that can simultaneously offer significant power savings and co-integration with wak ...

Beyond Scaling : Physics and Modeling for Pushing the Frontiers of Low-Power Devices

Luca De Michielis

Over the recent decades, the balance between increasing the complexity of computer chips and simultaneously reducing cost per bit has been accommodated by down-scaling. While extremely successful in the past, this approach now faces grave limitations leadi ...

Active Self-Switching Methods for Emerging Monolithic Bidirectional Switches Applied to Diode-Less Converters

Alfred Rufer, Daniel Siemaszko

This paper presents a recently introduced switching principle for emerging monolithic bidirectional devices. Based on the hypothesis that those switches may overcome conventional diode type solutions in power converters, an active self-switching process be ...

Micro-Electro-Mechanical Metal-Air-Insulator-Semiconductor Diode Switch

Mihai Adrian Ionescu, Didier Bouvet, Donatello Acquaviva

The design, fabrication and characterization of Micro-electro-mechanical metal-air-insulator-semiconductor (MEM-MAIS) diode switch are originally reported. An abrupt switching from off-state to Fowler-Nordheim tunneling current in on-state is induced by th ...

Enhanced spontaneous emission in a photonic-crystal light-emitting diode

Laurent Balet, Blandine Alloing

We report direct evidence of enhanced spontaneous emission in a photonic-crystal (PhC) light-emitting diode. The device consists of p-i-n heterojunction embedded in a suspended membrane, comprising a layer of self-assembled quantum dots. Current is injecte ...

Non-Linear Properties and Efficiency Improvements of a Bi-Directional Isolated DC-AC Converter with Soft Commutation

Alfred Rufer, Christophe Chabert

This paper presents the operation principle and the properties of a single-phase DC-AC converter with medium frequency transformer and soft commutation. The influence of the non-dissipative snubber capacitor and the transformer parasitic components for ZVS ...
