Lithium-niobate-based narrow-linewidth frequency agile integrated lasers with petahertz frequency tuning rate

Tobias Kippenberg, Junqiu Liu, Rui Ning Wang, Johann Emmeram Riemensberger, Anat Siddharth, Guanhao Huang, Mikhail Churaev, Viacheslav Snigirev

We demonstrate an electro-optically tunable hybrid integrated laser self-injection locked to a mode of a heterogeneously integrated lithium-niobate-on-Damascene-silicon-nitride microresonator. An intrinsic linewidth of 3 kHz and a frequency tuning rate of ...

Automatic Call Sign Detection: Matching Air Surveillance Data with Air Traffic Spoken Communications

Petr Motlicek

Voice communication is the main channel to exchange information between pilots and Air-Traffic Controllers (ATCos). Recently, several projects have explored the employment of speech recognition technology to automatically extract spoken key information suc ...

Electronic localization in CaVO3 films via bandwidth control

Thorsten Schmitt

Understanding and controlling the electronic structure of thin layers of quantum materials is a crucial first step towards designing heterostructures where new phases and phenomena, including the metal-insulator transition (MIT), emerge. Here, we demonstra ...

Generalization of Referenceless Timing Mismatch Calibration Methods for Time-Interleaved ADCs

Yusuf Leblebici, Mustafa Kilic, Arda Uran

Calibration of time-interleaved analog-to-digital converters is a problem whose necessity and complexity increase with the number of interleaved channels. In this study, we develop a generic representation of the referenceless timing mismatch calibration s ...

A Hybrid CDAC-Threshold Configuring SAR ADC in 28nm FDSOI CMOS

Yusuf Leblebici, Mustafa Kilic

In this paper, a 9-bit 1.3 GS/s single channel SAR ADC is presented. In conventional SAR ADCs, the capacitive DAC size grows exponentially with respect to converter resolution. This results in both signal bandwidth and conversion speed reduction. The propo ...

Micro-fabrication of high-thickness spiral inductors for the remote powering of implantable biosensors

Giovanni De Micheli, Sandro Carrara, Jacopo Olivo

A micro-fabrication process is proposed to realize high-thickness spiral inductors for the remote powering of implantable biosensors through inductive link. The process is suitable for different substrates, such as silicon and Pyrex, and enables the fabric ...

Optimal input design for direct data-driven tuning of model-reference controllers

Alireza Karimi

In recent years, direct data-driven controller tuning methods have been proposed as an alternative to the standard model-based approach for model-reference control design. In this work, the problem of input design for noniterative direct data-driven techni ...

Looking Inside Modern Receivers

Pierre-André Farine, Cyril Botteron

The principle of wireless communications originates from the need to communicate between two points separated by a distance sufficiently large to prevent the use of wires. This article talks about modern receivers in which the basic building blocks of mode ...

Centre frequency and bandwidth tunable bandpass filter based on RF MEMS (10-14 GHz)

Mihai Adrian Ionescu, Catherine Dehollain, Montserrat Fernandez-Bolanos Badia

This paper presents a novel tunable bandpass filter design with independent control of both the centre frequency and the bandwidth by means of analogue-series and digital-shunt MEMS capacitors. The filter is designed for operation in X and Ku bands with 4 ...
