Abstract:
A set of new analytical models for 3 dB cutoff frequency, 3 dB bandwidth and ripple of a series two-resonator microelectromechanical system(MEM)filter is presented. Seeing that the damping of the MEM filter is very small, a new analytical model for the ripple of the MEM filter is derived firstly. Then the magnitude response function of the MEM filter is expended in two-order Taylor series around two natural frequencies respectively. The new analytical models for 3 dB cutoff frequency, 3 dB bandwidth are derived based on the fact that the first derivative of the magnitude response function is near zero at the two natural frequencies. The set of new models is validated by comparing its results with the results from conventional method.
