Digitally-Tunable Surface Acoustic Wave Resonator, Robert Russell Hay
Boise State University Theses and Dissertations
Surface acoustic wave (SAW) technology has been utilized in numerous research and commercial devices since the practical implementation was enabled by the availability of suitable photolithographic techniques in the 1970s. With the traditional approach to implementing these devices the frequency response is established during manufacture. This dissertation proposes a different approach to implementing a SAW device. The SAW structure is added to the top of an integrated circuit so that the frequency response can be digitally controlled and the peak resonant frequency can be varied. The approach is based on implementing a phase-controlled interface between the SAW transducer fingers and …
