摘 要：The ever increasing need for regional and global roaming together with continuous advances in wireless communication standards continue to push future transceivers towards an ability to support multi-mode operation with minimal increases in cost, hardware complexity, and power consumption. RF channel-select filter banks pose a particularly attractive method for achieving multiband reconfigurability, since they not only provide the needed front-end reconfigurability, but also allow for power efficient and versatile transceiver designs, e.g., software-defined radio. Such channel-select filters, however, impose requirements on their constituent resonators that are not yet achievable on the micro-scale. Specifically, capacitively-transduced micromechanical resonators achieve highQ, but suffer from high impedance; while piezoelectric micromechanical resonators offer low impedance, but with insufficientQ. This dissertation demonstrates four new techniques to address the issues in both technologies.
