The key of implementing system level simulation of microelectromechanical systems (MEMS) is to create macromodels of them. The macromodel of single layer beam MEMS has been studied widely, but in reality MEMS is usually made of multi layer beams. A macromodel for multi layer beam MEMS based on force voltage (F V) analogy is proposed, the model is suitable for time and frequency domain analysis of small signals, it is useful to design of multi layer beam MEMS. Simulating results show that the model has high accuracy.
