Abstract

In methods and circuits for using associated circuitry to enhance performance of a micro-electromechanical switch, one of the method embodiments is a contact conditioning process including applying a time-varying voltage to the control element of a closed switch. In another embodiment, a voltage profile applied to the control element of the switch can be tailored to improve the actuation speed or reliability of the switch. In another method embodiment, the performance of a switch may be evaluated by measuring a performance parameter, and corrective action initiated if the switch performance is determined to need improvement. An embodiment of a circuit for maintaining performance of a micro-electromechanical switch includes first and second signal line nodes, sensing circuitry coupled to the signal line nodes and adapted to sense a performance parameter value of the switch, and control circuitry operably coupled to at least one terminal of the switch.
