Dynamic Analysis and State Feedback Voltage Control of Single-Phase Active Rectifiers with DC-Link Resonant Filters

Alfred Rufer, Michail Vasiladiotis

Single-phase active rectifiers exhibit an inherent strong second-order current harmonic on their DC-link. The latter is often undesirable from a load point of view and is therefore chosen to be eliminated. A common method is the use of a resonant passive L ...

Electron mobility extraction in triangular gate-all-around Si nanowire junctionless nMOSFETs with cross-section down to 5 nm

Mihai Adrian Ionescu, Jean-Michel Sallese, Wladyslaw Grabinski, Mohammad Najmzadeh, Matthieu Berthomé

In this paper, we report the first systematic study on electron mobility extraction in equilateral triangular gate-all-around Si nanowire junctionless nMOSFETs with cross-section down to 5 nm. 1 x 10(19) cm(-3) n-type channel doping, 5-20 nm Si nanowire wi ...

Beyond Scaling

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 ...

Properties of convective cells generated in magnetized toroidal plasmas

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Christian Gabriel Theiler, Joaquim Loizu Cisquella

Convective cells for turbulence control, generated by means of biased electrodes, are investigated in the simple magnetized toroidal plasmas of TORPEX. A two-dimensional array of 24 electrodes is installed on a metal limiter to test different biasing schem ...

Modeling methodology of high-voltage substrate minority and majority carrier injections

Maher Kayal, Jean-Michel Sallese, Fabrizio Lo Conte

This paper presents a modeling methodology for substrate current coupling mechanisms. An enhanced model of the diode ensuring continuity of minority carriers is used to build an equivalent schematic, accounting for minority and majority carrier propagation ...

On performance of series connected CMOS vertical hall devices

Radivoje Popovic, Mirjana Banjevic

Series connected (stacked) CMOS vertical Hall devices were analyzed on the basis of performance of a single five contacts device biased at different common mode voltages with respect to the substrate. The uneven influence of junction field effect on residu ...

Ferroelectric Gate on AlGaN/GaN Heterostructures

Nava Setter, Paul Muralt, Igor Stolichnov, Lisa Malin

A PZT, Pb(Zr,Ti)O-3 (40:60), ferroelectric layer has been successfully deposited onto a Al0.3Ga0.7N/GaN heterostructure with a 2DEG, two dimensional electron gas. Due to the chemical and temperature stability of AlGaN/GaN it was possible to implement the c ...

An Analysis of Flicker Noise Rejection in Low-Power and Low-Voltage CMOS Mixers

Christian Enz

The sensitivity of RF CMOS receivers using a direct conversion or a low-IF architecture is strongly affected by flicker noise. This paper gives theoretical guidelines to predict the flicker noise in Gilbert-cell mixers. The conversion gain, the equivalent ...
