Abstract

Micro-electro-mechanical relays with multiple gate electrodes (i.e., multiple input voltage signals), operated with a tunable body bias voltage, are investigated for more compact and energy-efficient implementation of digital logic circuits. Specifically, a relay design with three gate electrodes of equal area is demonstrated to be capable of performing different digital logic functions for the same input operating voltage ( {V} {textbf {DD}} ), by adjusting the body bias voltage. Since the lower limit for {V} {textbf {DD}} is equal to the switching hysteresis voltage ( {V} {textbf {H}} ), the magnitude of {V} {textbf {H}} is investigated for different combinations of transitioning input voltage signals. It is found that {V} {textbf {H}} is larger for fewer transitioning input voltage signals, i.e., reduced effective actuation area of the switching input voltage signal. This can set a practical upper limit for the number of independent gates in a single relay.
