Paper Abstract

High frequency, micromechanical bandpass filter, with tunable frequency and bandwidth are demonstrated in a polysilicon surface micromachining technology. These filter utilized a parallel-resonator architecture, in which properly phased outputs from two or more micromechanical resonators are combined to yield a desired filter spectrum. Damping effect was shown to have a significant factor in affecting the flat passband of the filter and will be further analyzed in this paper.
