Abstract
A switching apparatus, as may be configured to actuate stacked MEMS switches, may include a switching circuitry () including a MEMS switch () having a beam () made up of a first movable actuator () and a second movable actuator () electrically connected by a common connector () and arranged to selectively establish an electrical current path through the first and second movable actuators in response to a gate control signal applied to the gates of the switch to actuate the movable actuators. The apparatus may further include a gating circuitry () to generate the gate control signal applied to gates of the switch. The gating circuitry may include a driver channel () electrically coupled to the common connector and may be adapted to electrically float with respect to a varying beam voltage, and may be electrically referenced between the varying beam voltage and a local electrical ground of the gating circuitry.
