Journal ArticleDOI
In-plane acoustic reflectors for reducing effective anchor loss in lateral?extensional MEMS resonators
TL;DR: In this paper, in-plane acoustic reflectors are proposed to enhance the quality factor (Q) in lateral-mode micromachined resonators, which can reduce the overall anchor loss with minimum modification in the resonator design.
Journal ArticleDOI
A 76 dB $\Omega $ 1.7 GHz 0.18 $\mu$ m CMOS Tunable TIA Using Broadband Current Pre-Amplifier for High Frequency Lateral MEMS Oscillators
TL;DR: The TIA achieves the highest reported figure of merit (FoM) among lateral piezoelectric micromechanical oscillators and meets the phase-noise requirements for most 2G and 3G cellular standards including GSM 900 MHz, GSM 1800 MHz, and HSDPA.
Journal ArticleDOI
Turnover Temperature Point in Extensional-Mode Highly Doped Silicon Microresonators
TL;DR: In this paper, the authors showed that the turnover point in thin-film piezoelectric-on-silicon (TPoS) resonators is a function of doping concentration and orientation.
Proceedings ArticleDOI
Toward ultimate performance in GHZ MEMS resonators: Low impedance and high Q
TL;DR: In this paper, the authors reported a ∼1GHz lateral extensional thin-film piezoelectric-on-substrate (TPoS) resonator with an unloaded quality factor (Q) of 6700 in air (frequency-quality factor product of 6.6×1012), a motional impedance of ∼160Ω, and a linear thermal coefficient of frequency of −29ppm.
Journal ArticleDOI
Electronic Temperature Compensation of Lateral Bulk Acoustic Resonator Reference Oscillators Using Enhanced Series Tuning Technique
TL;DR: This paper reports on the demonstration of series tuning for lateral micromechanical oscillators and its application for electronic temperature compensation of piezoelectric lateral bulk acoustic resonator (LBAR) micromedical oscillators.
