Latest Patents

Rong Liu holds a patent titled "Frequency sensitivity analysis and optimum design for MEMS resonator." This patent presents a frequency stability analysis and design method for frequency robust resonators, such as MEMS resonators. The frequency characteristics of a laterally vibrating resonator are thoroughly analyzed. The patent derives the first and second order frequency sensitivities to fabrication errors, considering the sidewall structure. A crucial relationship is developed between the proof mass area and perimeter, and the beam width for single material structures. This relationship indicates that the proof mass perimeter times the beam width should equal six times the area of the proof mass. Design examples for both single material and multi-layer structures are provided. The principles and results from this patent can be applied to analyze and design other MEMS resonators.
