TSM-AW Sensors Based on Miller XCOs for Microgravimetric Measurements in Liquid Media

Abstract

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.
