Multiple-Input Relay Design for More Compact Implementation of Digital Logic Circuits

Multiple-input relays are proposed to enable more compact implementation of digital logic circuits, and the first functional prototypes are presented. A relay with three equally sized input electrodes is demonstrated to perform various three-input logic functions, with a delay that can be well predicted by a lumped-parameter model. Relays with differently sized input electrodes can be used to perform more complex functions. A flash-type analog-to-digital converter is presented as one example.
