Microelectromechanical systems (MEMS) are becoming important for all kinds of industrial applications. Among
them are filters in communication devices, due to the growing demand for efficient and accurate filtering of signals. In recent
developments single degree of freedom (1-dof) oscillators, that are operated at a parametric resonances, are employed for
such tasks. Typically vibration damping is low in such MEM systems. While parametric excitation (PE) is used so far to
take advantage of a parametric resonance, this contribution suggests to also exploit parametric anti-resonances in order to
improve the damping behavior of such systems. Modeling aspects of a 2-dof MEM system and first results of the analysis of
the non-linear and the linearized system are the focus of this paper.
