A 0.14-nJ/b 200-Mb/s 2.7-3.5-GHz Quasi-Balanced FSK Transceiver With PLL-Based Modulation and Sideband Energy Detection
This paper describes a balanced frequency shift keying (FSK) modulation, namely quasi-balanced FSK (QB-FSK), for energy-efficient high-data-rate communication. Not suffering from data-pattern dependency, the proposed modulation method enables frequency mod ...
Piscataway2024A 5G n77 Filter Using Shear Bulk Mode Resonator With Crystalline X-cut Lithium Niobate Films
This paper presents the use of a shear bulk acoustic mode resonator made of a membrane of X-cut lithium niobate (LiNbO3) for ultra-wide band filter applications. Aluminum interdigitated (IDT) electrodes are deposited on top of the LiNbO3 thin film as well ...
IEEE2023Transversal Spurious Mode Suppression in Ultra-Large-Coupling SH0 Acoustic Resonators on YX36 degrees-Cut Lithium Niobate
Luis Guillermo Villanueva Torrijo, Silvan Stettler
This work reports on the design and fabrication of fundamental shear horizontal (SH0) mode acoustic resonators based on a suspended lithium niobate (LNO) film at 1.04 GHz. Due to the large e16 piezoelectric coefficient of YX36 degrees.-cut LNO, fabricated ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2023Methods for Calibrating the Electrochemical Quartz Crystal Microbalance: Frequency to Mass and Compensation for Viscous Load
Stefano Mischler, Anna Neus Igual Muñoz
The main output from an Electrochemical Quartz Crystal Microbalance is a frequency shift. This note describes how to separate the mass- and viscous load contributions to this shift by a calibration procedure. The mass calibration is made by electroplating ...
MDPI2023Lithium-niobate-based narrow-linewidth frequency agile integrated lasers with petahertz frequency tuning rate
Tobias Kippenberg, Rui Ning Wang, Guanhao Huang, Anat Siddharth, Mikhail Churaev, Viacheslav Snigirev, Junqiu Liu
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 ...
IEEE2023A Cryo-CMOS Wideband Quadrature Receiver With Frequency Synthesizer for Scalable Multiplexed Readout of Silicon Spin Qubits
Edoardo Charbon, Andrea Ruffino, Yatao Peng
In this article, a cryo-CMOS receiver integrated with a frequency synthesizer for scalable multiplexed readout of qubits is presented, focusing on radio frequency (RF) reflectometry readout of silicon-based semiconductor spin qubits/quantum dots. The propo ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Energy-Efficient Design Techniques for High-Speed Wireline Serial Links
The exponential growth in computing power and multimedia services has caused a tremendous increase in data traffic in recent years. This increase in data traffic brings a strong demand for data bandwidth of electrical input/output (I/O) links and pushes th ...
EPFL2021Monolithic piezoelectric control of soliton microcombs
Tobias Kippenberg, Rui Ning Wang, Junqiu Liu, Erwan Guillaume Albert Lucas, Wenle Weng, Arslan Sajid Raja, Jijun He, Miles Henry Anderson, Tianyi Liu
High-speed actuation of laser frequency(1)is critical in applications using lasers and frequency combs(2,3), and is a prerequisite for phase locking, frequency stabilization and stability transfer among optical carriers. For example, high-bandwidth feedbac ...
NATURE PUBLISHING GROUP2020Evidence of Smaller 1/F Noise in AlScN-Based Oscillators Compared to AlN-Based Oscillators
Luis Guillermo Villanueva Torrijo, Marco Liffredo, Andrea Lozzi
In this paper we investigate the direct effect of resonator quality factor (Q) on the oscillator phase noise. We use 2-port contour mode resonators (CMRs), fabricated both with aluminum nitride (AlN) and aluminum scandium nitride (AlScN), as the frequency- ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2020Performance of chip-scale optical frequency comb generators in coherent WDM communications
Optical frequency combs have the potential to become key building blocks of wavelength-division multiplexing (WDM) communication systems. The strictly equidistant narrow-band spectral lines of a frequency comb can serve either as carriers for parallel WDM ...
