Measurement and thermal modeling of high-Q piezoelectric resonators

This paper presents experimental data from the determination of the equival ent electrical circuit parameters of AT-cut quartz resonators and the measu rement technique used. From an analysis of the experimental data it is poss ible to determine the equations which represent the variations of the param eters versus temperature. The models can then be used in simulation program s to determine the thermal behavior of the frequency of devices which use q uartz crystal in their configuration and which require high stability. PSpi ce circuit simulation and experimental results are also included. (C) 2000 Elsevier Science Ltd. All rights reserved.
