Synthesis of Optical Filters Using Sagnac Interferometer in Ring Resonator
We propose a new synthesis method for the implementation of infinite impulse response filters, using a Sagnac interferometer within a ring resonator. This structure permits the synthesis of second-order optical functions ...
Narrowband feedback for narrowband control of resonant and non-resonant vibration
This paper presents a simple feedback methodology that uses second order filters to control narrowband resonant and non-resonant vibration of a structural system. In particular, a single degree-of-freedom system is studied ...
Design of a CMOS second order band-pass continuous time filter using numerical optimization
(IEEE Int. Midwest Symp. Circuits and Systems, 2009-08)
A TRIPLE-MODE BANDPASS FILTER USING A MODIFIED CIRCULAR PATCH RESONATOR
(JOHN WILEY & SONS INC, 2009)
This article presents a triple-mode bandpass filter using a modified circular patch resonator. Etched slots in the resonator split the TM(1, 1, 0)(z) degenerate fundamental modes and also perturb the TM(2, 1, 0)(z) mode, ...
Practical active control of cavity noise using loop shaping: Two case studies
A simple loop shaping technique is applied to design an optimal, robust feedback controller to reduce the interior noise of an acoustic cavity. It is a data-based technique that uses the measured plant response to tune the ...
Design constraints for third-order PLL nodes in master-slave clock distribution networks
(ELSEVIER SCIENCE BV, 2010)
Clock signal distribution in telecommunication commercial systems usually adopts a master-slave architecture, with a precise time basis generator as a master and phase-locked loops (PLLs) as slaves. In the majority of the ...
Low power consumption silicon photonics tuning filters based on compound microring resonators
Scalable integrated optics platforms based on silicon-on-insulator allow to develop optics and electronics functions on the same chip. Developments in this area are fostered by its potential as an I/O technology that can ...
Turning a loudspeaker into an active Helmholtz resonator: Underlying law, principle and design methodology
This paper is concerned with how to turn a moving-coil loudspeaker into an active Helmholtz resonator (AHR): that is, an active noise control loudspeaker used in conjunction with a microphone and a feedback controller to ...
