Review of SAW oscillator performance

Abstract

State-of-the-art phase noise performance has been demonstrated for both surface acoustic wave (SAW) r e s o n a t o r a n d d e l a y l i n e s t a b i l i z e d oscillators [l -51. The same basic feedback-loop oscillator design philosophy 16, 71 was applied i n each case in order to achieve these results. This paper reviews the design, fabrication, component selection, a n d performance for a n extremely low-noise SAW resonator hybrid circuit oscillator. Finally, s e v e r a l r e c e n t r e s u l t s including t h e flicker noise of SAW resonator devices a n d the vibration sensitivity of all quartz package SAW r e s o n a t o r s a r e d i s c u s s e d i n t h e c o n t e x t of p o t e n t i a l S A W o s c i l l a t o r p e r f o r m a n c e enhancements.

Multi-frequency pierce oscillators based on piezoelectric AlN contour-mode MEMS resonators

“…Such a solution is very well suited for next-generation reconfigurable and multi-band wireless [19,20] applications. Indeed, further developments both at the circuit design and resonator levels need to be made to match the phase noise performance of state-of-the-art SAW oscillators [21].…”

Packageless temperature sensor based on AlN/IDT/ZnO/Silicon layered structure

“…Electro-acoustic properties of isolated wave, such as propagation velocity and electromechanical coupling are highly dependent on the nature, thickness and geometrical configuration of the materials composing WLAW device. To this date, few studies have been reported in the literature on this type of structure [1,[5][6][7]. The successful confinement of WLAW in structures based on SiO 2 guiding layer was reported by Zhgoon et al [1,7].…”
