碩士 === 國立海洋大學 === 電機工程學系 === 90 === The simulation, design and application of surface acoustic wave (SAW) resonators are performed systematically. First, the equivalent circuit model simulating SAW devices utilizing the commercial simulation software, the Microwave Office was discussed. Some of the parameters of equivalent circuit model will be extracted from the coupling-of-mode (COM) model. Finally, the correction of simulation of the interdigital transducer (IDT) and grating will be verified by comparing with existing results by other researchers. Subsequently, the discussion focuses on the theory and analysis method of one port surface acoustic wave resonator. The design flow will be proposed and verified by using the equivalent circuit model and a 400MHz one port SAWR design example will be given to show its validity. Finally, the design of a low jitter clock generator will be discussed and a 418MHz SAW based clock generator is presented as an example to show the validity of the feedback oscillator analysis method. From the simulation-design-application sequence, some useful information may be derived for designing an ultra-low jitter clock generator.
