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

Pasquale Scarlino

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 ...

Electromechanically induced absorption in a circuit nano-electromechanical system

Tobias Kippenberg, Xiaoqing Zhou, Albert Schliesser

A detailed analysis of electromechanically induced absorption (EMIA) in a circuit nano-electromechanical hybrid system consisting of a superconducting microwave resonator coupled to a nanomechanical beam is presented. By performing two-tone spectroscopy ex ...

Parametric feedback oscillators

Luis Guillermo Villanueva Torrijo

A parametric feedback oscillator includes a resonator which has at least one transduction element and at least one electromechanical resonating element. The resonator is configured to accept as input a parametric excitation signal at a frequency 2[omega]0 ...

A Nanoscale Parametric Feedback Oscillator

Luis Guillermo Villanueva Torrijo

We describe and demonstrate a new oscillator topology, the parametric feedback oscillator (PFO). The PFO paradigm is applicable to a wide variety of nanoscale devices and opens the possibility of new classes of oscillators employing innovative frequencydet ...

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 ...
