| Abstract: | Aimed at the cantilever beam structure which can stand for the characteristic of MEMS devices, standard polynomial controlled sources of SPICE are introduced to build multi mode small signal macromodel of equivalent circuit for cantilever beam. Under the force loaded outside, the output voltage amplitude frequency response characteristic of distributed parameter force sensor is presented, by the system simulation to the cantilever beam macromodel and periphery circuits with SPICE. The resonance frequencies of each modal and related curves of the model are verified with the COVENTORWARE software. |
