A Self-Regulating Oscillator for Sensor Operation of Nanoelectromechanical Systems

Maher Kayal, Marc Pastre, Christian Kauth

A closed-loop oscillator topology is proposed for dynamic sensor operation of nanoelectromechanical systems, benefiting from the structure's quality factor. Automatic adaptation to diverse sensors' properties is achieved via a self-regulating phase-locked ...

Elastomer based tunable optofluidic devices

Demetri Psaltis, Andreas Vasdekis, Wuzhou Song

The synergetic integration of photonics and microfluidics has enabled a wide range of optofluidic devices that can be tuned based on various physical mechanisms. One such tuning mechanism can be realized based on the elasticity of polydimethylsiloxane (PDM ...

Fano resonant plasmonic systems: Functioning principles and applications

Olivier Martin, Andrea Lovera, Benjamin Gallinet, Thomas Gerd Siegfried

Using a generalization of Fano formula that includes the intrinsic losses associated with metals, we retrieve the underlying modal structure that produces Fano resonances from the interference between a bright and a dark mode. This knowledge is used to det ...

Low-Power and Widely-Tunable Linearized Biquadratic Low-Pass Transconductor-C Filter

Seyed Armin Tajalli, Yusuf Leblebici

A sixth-order low-pass

g_m

-C filter with a very wide tuning range (

f_c

= 100 Hz to 10 MHz) is presented. The wide tuning range has been achieved without using switchable components or programmable building blocks. A single stage folded-cascode transcon ...

Effect of mechanical loading on the tuning of acoustic resonances in Ba (x) Sr1-x TiO3 thin films

Nava Setter, Alexander Tagantsev, Andreas Nöth

The effect of mechanical loading on the tuning performance of a tunable Thin Film Bulk Acoustic Wave Resonator (TFBAR) based on a Ba0.3Sr0.7TiO3 (BST) thin film has been investigated experimentally and theoretically. A membrane-type TFBAR was fabricated by ...

A 9 pW/Hz Adjustable Clock Generator with 3-Decade Tuning Range for Dynamic Power Management in Subthreshold SCL Systems

Seyed Armin Tajalli, Yusuf Leblebici

A widely-tunable and power-scalable clock generator for ultra-low power (ULP) applications is presented. Benefitting from a novel self-adjustable loop frequency response, the proposed phase-locked loop based clock generator exhibits a tuning range of three ...

Colossal electroresistance and colossal magnetoresistance in spinel multiferroic CdCr2S4

Helmuth Berger

Colossal magnetoresistance (CMR) and colossal electroresistance (CER) induced by the electric field in spinel multiferroic CdCr2S4 are reported. It is found that a metal-insulator transition in CdCr2S4 is triggered by the electrical field. In magnetic fiel ...
