ABSTRACT:
A reconfigurable circuit and a related method for its use, the circuit including multiple microelectromechanical systems (MEMS) switches connected between selected points in the circuit. The MEMS switches are controlled to select a desired circuit condition, such as an impedance matching condition, and then the switch conditions may be fused permanently. In the context of an impedance matching circuit, the MEMS switches may be used to optimize matching after circuit fabrication or after packaging, thereby allowing optimization even after potentially performance changing events.
