Design and Fabrication of Tri-Stopband Bandstop Filters Using Cascaded and Multi-Armed Methods

open access: yesAdvanced Electromagnetics, 2017
In this paper, we proposed a compact C-open-loop ring resonator and its equivalent circuit. The second cascaded BSF are designed using this simple C-ring resonator.

Independently Tunable Concurrent Dual-Band VCO Using Square Open-Loop Resonator

open access: yesIEEE Access, 2018
A concurrent dual-band voltage-controlled oscillator (VCO) with independently tunable dual oscillation frequencies is proposed. A shared square open-loop dual-mode resonator and two varactor diodes are the basic units offering flexible tuning for the ...

Multi-coefficient eigenmode operation—breaking through 10°/h open-loop bias instability in wideband aluminum nitride piezoelectric BAW gyroscopes

open access: yesMicrosystems & Nanoengineering, 2023
In this paper, a modification to the eigenmode operation of resonant gyroscopes is introduced. The multi-coefficient eigenmode operation can improve cross-mode isolation due to electrode misalignments and imperfections, which is one of the causes of ...

Short-Circuited Stub-Embedded Ring Resonator and its Application in Diplexer

open access: yesIEEE Access, 2019
Two types of short-circuited stub-embedded ring resonators (SERRs) are proposed in this paper. The resonant modes of the SERR can be designed by properly choosing the short-circuited point on the resonator.

The PS 10 MHz High Level RF System Upgrade [PDF]

open access: yes, 2016
In view of the upgrade of the injectors for the High Luminosity LHC, significantly higher bunch intensity is required for LHC-type beams. In this context an upgrade of the main accelerating RF system of the Proton Synchrotron (PS) is necessary, aiming at

Feedback control of persistent-current oscillation based on the atomic-clock technique

open access: yes, 2018
We propose a scheme of stabilizing the persistent-current Rabi oscillation based on the flux qubit-resonator-atom hybrid structure. The LC resonator weakly interacts with the flux qubit and maps the persistent-current Rabi oscillation onto the ...

Frequency Precision of Oscillators Based on High-Q Resonators [PDF]

open access: yes, 2015
We present a method for analyzing the phase noise of oscillators based on feedback driven high quality factor resonators. Our approach is to derive the phase drift of the oscillator by projecting the stochastic oscillator dynamics onto a slow time scale ...

Fast tuning of superconducting microwave cavities

open access: yes, 2008
Photons are fundamental excitations of the electromagnetic field and can be captured in cavities. For a given cavity with a certain size, the fundamental mode has a fixed frequency {\it f} which gives the photons a specific "color". The cavity also has a
