Zusammenfassung:The down-conversion performance of a multimodal microelectromechanical mixer-filter is improved over 30 B by parametric amplification. The input signal is an AM-modulated signal with a carrier frequency of 0.5 Hz. The obtained amplification is shown to depend on the particular eigenmode in predetermined way due to the configuration of the electrodes used to excite and amplify the resonance.
