A CMOS-MEMS filter using a V-coupler and electrical phase inversion

In this paper a fully integrated CMOS-MEMS filter is presented. The filter is formed by two beams using a V-shaped coupler which allows the in-plane vibrations. The device presents a BW of 1.85 MHz for a 29 MHz center frequency. The electrical phase inversion mechanism is used in order to obtain the filter response. The…
