A direct energy balance method for approximating envelope decay of oscillating MEMS structures.
The real pole component (envelope decay coefficient) of an oscillating microelectromechanical systems (MEMS) structure is calculated directly in the energy domain without using an equation of motion. Similar to the simplified Rayleigh frequency calculation in which maximum potential and kinetic energy are equated, our method equates the initial minus dissipated energy to present energy.
