Perfectly Complementary Relay Design for Digital Logic Applications

A dual-ended (¿seesaw¿) relay design is proposed for ultralow-power digital logic applications. Fabricated seesaw relays demonstrate a perfectly complementary switching behavior that is symmetric about

/2, with extremely steep switching behavior (< 0.1 mV/dec) and low on -state resistance (< 1 k¿). The perfectly complementary and symmetric operation provides for maximum operating voltage margin and minimal crowbar current, as evidenced by an abrupt inverter voltage transfer characteristic.
