Investigation of Tunable Piezoelectric Resonators

在本项目中，将探索用于频率控制和机电滤波器应用的可调谐压电谐振器的概念。这项研究的核心是利用并联电容来调谐压电谐振器的技术。这一概念在将机械谐振器用作频率源的应用(包括电子和射频通信应用)和机电滤波中特别有用。为了充分利用和提高谐振器的频率，最大化调谐范围和品质因数，了解谐振器的温度-频率特性。该提案提出了一项三年研究计划，以解决这些问题和其他问题。研究的影响将通过产生和传播与频率控制界有关的知识来实现。这项研究也将通过对学生的培训产生影响。除了研究生，本科生和高中生将通过匹兹堡大学一项名为皮特工程职业准入计划的新的多样性倡议参与该项目。

In this project, tunable piezoelectric resonator concepts will be explored for use in frequency control and electromechanical filter applications. The centerpiece of the research is a technique for tuning piezoelectric resonators through the use of shunt capacitance. This concept can be particularly useful in applications in which mechanical resonators are used as frequency sources (including electronics and radio frequency communications applications) and in electromechanical filtering. In order to fully exploit increasing the resonator frequency, maximizing the tuning range and quality factor, and understanding the temperature-frequency characteristics of the resonator. This proposal presents a three-year research plan to address these and other issues. The impact of the research will be made through the generation and dissemination of knowledge that will be pertinent to the frequency control community. The research will also have impact through the training of students. In addition to graduate students, undergraduate and high school students will involved in the project through a new diversity initiative at the University of Pittsburgh called the Pitt Engineering Career Access Program.
