到目前为止，基于高稳定性经典配置的石英晶体控制振荡器（XCO）设计成功与否，在阻尼介质中用作微重力厚度剪切模式声波（TSM-AW）传感器，在很大程度上取决于设计者的能力和经验。石英经历的强阻尼条件意味着有必要调整设计，以便尽管其品质因数降低，但仍能保持振荡。尽管各个作者付出了巨大的努力，但用于阻尼介质的电子电路振荡器的设计方法尚不存在。这是由于研究振荡条件及其作为应用函数的可能优化的难度。在本文中，我们提出了一种方法来帮助设计人员开发用于液体介质中高分辨率微重力应用的 TSM-AW 传感器，例如化学物质检测、用于分子识别的生物传感器等。提出了基于米勒拓扑实现传感器振荡器的方法。
Up to now, the success of the design of quartz crystal-controlled oscillators (XCOs) based on high-stability classical configurations for uses as microgravimetric thickness-shear-mode acoustic-wave (TSM-AW) sensors in damping media has strongly depended on the ability and experience of the designer. The conditions of strong damping that quartz experiences imply the necessity to adapt the designs so that the oscillation stays in spite of the reduction of its quality factor. Despite all the efforts developed by various authors, a methodology of the design of electronic circuit oscillators for their use in damping media does not exist yet. This is due to the difficulty of the study of the oscillation condition and its possible optimization as a function of the application. In this paper, we propose a methodology to aid designers in developing TSM-AW sensors for high-resolution microgravimetrical applications in liquid media, such as detection of chemical species, biosensors for molecular recognition, etc. Approaches are presented to carry out sensor oscillators based on the Miller topology.
