Fully integrated FBAR sensor matrix for mass detection
Procedia Chemistry, 2009 A fully integrated Film Bulk Acoustic Resonator (FBAR) based mass detection sensor matrix was developed for label-free in-vitro DNA and protein diagnostics. A 64 pixels sensor matrix was post-processed on top of a CMOS readout circuitry at wafer level. A

A study on FBAR Filters reconfiguration
2005 12th IEEE International Conference on Electronics, Circuits and Systems, 2005This paper presents the possibilities to reconfigure the Film Bulk Acoustic Resonator (FBAR) Filters. We propose the addition of passive elements (L, C) to the FBAR. An augmentation of 35% to the bandwidth is found when adding inductances, and a reduction of 32% is established when using capacitances.

An Investigation of Lateral Modes in FBAR Resonators
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2016Using first principles and the constitutive equations for a piezoelectric, we solve the 2D acoustic wave inside a single, infinite, piezoelectric membrane in order to study the dispersion of Thin Film Bulk Acoustic Resonator (FBAR) lateral modes, with and without infinitely-thin electrodes.

Oven controlled FBAR oscillator
2015 IEEE International Ultrasonics Symposium (IUS), 2015Recent work with chip scale integrated FBAR oscillators has highlighted the fact that the temperature sensitivity is similar to SAW resonators. This sensitivity is significantly higher than quartz crystal oscillators, and limits the application of the technology. This investigation looks at the feasibility of stabilizing the frequency of the oscillator

In this chapter, the conventional models of acoustic resonators, such as Mason, KLM, and Lakin, are considered as a general background and possibility of their application (with adequate modifications) for modelling of the tuneable FBARs. In ferroelectric-based tuneable FBARs, the basic parameters, stiffness, acoustic velocity, and relative dielectric ...

FBAR is composed of piezoelectric film, electrodes and supporting layer or Bragg acoustic reflector. The performance of FBAR depends on the acoustic and electric properties of the materials. Based on the acoustic theory, we can deduce the plane-wave-propagating characteristics of the general elastic films and piezoelectric film in FBAR and then obtain ...
