The year 2013 was a very productive year, yielding three best paper awards: one for the first silicon nitride optomechanical oscillator, a second for the first micromechanical resoswitch-based on-chip charge pump, and a third for a wine-glass disk resonator Pierce oscillator with a best in class phase noise figure of merit. Another resoswitch power amplifier also emerged that also performed a filtering function. Perhaps one of the most ground-breaking disseminations this year was the exposition of the role extremely high Q micromechanical resonators and filters could play in enabling spectrum sensing software-defined cognitive radio–a concept that continues to drive research towards single-chip integration of MEMS directly over transistors.
