With quality factors (Q) often-exceeding 10,000, vibrating micromechanical resonators have emerged as leading candidates for on-chip versions of high-Q resonators used in wireless communications systems. However, as in the case for transistors, extending the frequency of MEMS resonators generally entails scaling of resonator dimensions. Unfortunately, smaller size often coincides with lower-power handling capability and increased motional impedance. In this talk, I will introduce novel solid-state transduction techniques, present latest results on narrow-bandwidth parametric filters for frequency-agile radio receivers, discuss performance scaling of MEMS resonators to X-band frequencies and propose mechanisms for coupling MEMS resonators with silicon photonics, spin-torque oscillators and mechanical systems in the quantum regime.
