Abstract
Piezoelectric resonators are used in electronic devices and electrical circuits as a frequency source. The most commonly used material for the piezoelectric resonators is quartz. The quartz resonator has a tunability of between 10 ppm (0.001%) and 100 ppm (0.01%) of the nominal frequency of operation. This work shows that greater tunability can be achieved using resonators made using piezoelectric materials other than quartz and a shunt-tuning technique. The tuning afforded by using lead zirconate titanate as the piezoelectric material in a cantilever type resonator is explored in detail from an analytical and experimental standpoint. It is shown that this tuning can be up to over 10,000 ppm (1%) of the nominal operational frequency in the configuration looked at, which was not optimized to maximize the tuning range. Questions of implementation of the resonator in a commonly used resonator circuit were also answered. The resonator was experimentally shown to be operable in a modified Pierce circuit with a tuning range that was analytically predicted.
