| Abstract: | A method for MEMS system-level simulation is proposed,which is based on the force analysis of the moving device.And combined with the energy principle,the coupling process is implemented by feedback mechanism of controlled sources.Then the equivalent circuit macromodel is developed,which is used to carry out the system-level simulation of the dynamic behavior of the electromechanics coupled thin membrane.Simulation results in Spice are compared with that in FEM and Saber,verifying such simulation method can be applied to the case of 2-D. |
