Abstract

State of the art analog to digital conversion at the edge prioritises either low power consumption, or environmental resilience. Nanoelectromechanical relays show promise as a solution to both with low leakage current and operation within elevated temperatures and radiation levels. This paper introduces an analog to digital flash converter design constructed from four- terminal nanoelectromechanical relays, each selectively biased to partition the voltage domain. Supported by three-terminal relays forming a binary encoder, 2-bit and 3-bit implementations of the design are simulated in Cadence to give estimates for sampling rates (444 kHz,278 kHz) and power consumption (15.58 µW,32.95 µW).
