摘要

BVA technologies for piezoelectric resonators have been introduced in the late 70's (1976,1977, 1978). Since then, a lot of work dealing with BVA resonators has been done in our laboratory and also in several other laboratories including industry laboratories. BVA oscillators have been designed to match BVA resonators special properties. BVA resonators and oscillators are now commercially available from at least 3 companies. Due to their special structure, BVA resonators (monolithic and often "electrodeless") happen to be an efficient tool to obtain an interesting link between the properties of resonators and oscillators and the properties of piezoelectric material (usually quartz).rnUnder those conditions, a review devoted to BVA resonators and oscillators may be useful because there is a need of summarizing existing results and because some results have never been published yet. This is the case for some recent results dealing with space applications of BVA resonators and oscillators. This is also the case for connection of resonators and oscillators parameters with material's properties.rnIn this paper, after a fast introduction replacing BVA technologies in the general frame of resonator's technology evolution, various type of BVA resonators are presented (including tactical type) and BVA technologies are rapidly discussed with use of AT, SC and eventually BT cuts. Results obtained by various authors are presented.rnIn a second section, we explain why BVA oscillators must be specially designed so as to match resonator characteristics and obtain best results in σ_y (τ) and drift.rnA special section is devoted to results obtained under hard environmental conditions (accelerations, vibrations, magnetic field, temperature and pressure changes, radiations, ...). Some results needed for space applications are presented.rnSince, unfortunately, space applications are very demanding, piezoelectric material quality may be a serious limitation to satisfy certain space requirements. Then, a section is devoted to the link between properties of the material with parameters measured on resonators or oscillators. This includes possible contributions of material's defects and fabrication technologies to flicker noise level of oscillators.rnAs a conclusion, results are discussed in terms of future trends and evolution of quartz frequency standards.
