Analog MEMS with non-linear support

摘要

The disclosed embodiments reveal an analog MEMS device with a pivotal micromirror that is supported by one or more beams that provide non-linear resistance. An electrode can electrostatically attract the micromirror, while the beam(s) provide resistance to deflection. When the forces equalize, the micromirror is held at a target angle. The beam support disclosed in the embodiments is superior to conventional torsion hinge supports, because it provides non-linear support for the micromirror, better matching the non-linear nature of the electrostatic force.
