Abstract

The present invention generally relates to a method of operating a MEMS DVC while minimizing impact of the MEMS device on contact surfaces. By reducing the drive voltage upon the pull-in movement of the MEMS device, the acceleration of the MEMS device towards the contact surface is reduced and thus, the impact velocity is reduced and less damage of the MEMS DVC device occurs.
