Excitation of a Si/SiGe quantum dot using an on-chip microwave antenna

We report transport measurements on a Si/SiGe quantum dot subject to microwave excitation via an on-chip antenna. The response shows signatures of photon-assisted tunneling and only a small effect on charge stability. We also explore the use of a d.c. curr ...

Temporally aliased video microscopy: an undersampling method for in-plane modal analysis of microelectromechanical systems

Martinus Gijs, Christophe Yamahata, Marc Stranczl

A simple optical method is proposed for performing in-plane experimental modal analysis of micromachined structures with a conventional charge-coupled device (CCD) camera. The motion of a micromechanical device actuated by high frequency sinusoidal forces ...

Passive Phase Noise Cancellation Scheme

Luis Guillermo Villanueva Torrijo

We introduce a new method for reducing phase noise in oscillators, thereby improving their frequency precision. The noise reduction is realized by a passive device consisting of a pair of coupled nonlinear resonating elements that are driven parametrically ...

Ultrafast Clock Recovery and Sampling by Single Parametric Device

Camille Sophie Brès

We propose and demonstrate a new architecture that combines clock recovery and signal processing functions in a single fiber device. By using parasitic cross-phase modulation of idler wave generated within the parametric sampling gate, rate-variable self-s ...

Halved Vivaldi Antenna With Reconfigurable Band Rejection

Julien Perruisseau-Carrier

This letter presents a Vivaldi antenna having the capability of dynamically rejecting interferers, mainly aiming at multistandard communication with dynamic frequencies allocation. Only half of the Vivaldi is used and placed over a ground plane, which is s ...

Human-Robot Synchrony: Flexible Assistance Using Adaptive Oscillators

Auke Ijspeert, Jesse van den Kieboom, Renaud Ronsse

We propose a novel method for movement assistance that is based on adaptive oscillators, i. e., mathematical tools that are capable of extracting the high-level features (amplitude, frequency, and offset) of a periodic signal. Such an oscillator acts like ...

Characterization of Distortionless Analog Signal Multicasting by Parametric Mixer

Camille Sophie Brès

We present characterization of a two-pump parametric device for analog linear multicasting. Linearity of parametric multicasting is assessed from highly linearized input seed by two-tone intermodulation measurements. Experimental results confirm distortion ...
