Abstract

High voltage micro-electromechanical systems (MEMS) switches are described. A MEMS teeter-totter switch can include a beam coupled to an anchor on a substrate and two control electrodes, disposed on a surface of the substrate. A control circuit may include an optical isolator that provides an isolated activation voltage to a voltage supply and control circuit. The voltage supply and control circuit uses the isolated activation voltage to supply a control voltage to one of the control electrodes with respect to a first reference voltage, causing the beam to provide an input voltage received from an input terminal to a contact electrode of the MEMS teeter-totter switch electrically connected to an output terminal. The input voltage is applied on the beam with respect to a second reference voltage different from the first reference voltage.
