Nanoelectromechanical analog-to-digital converter for low power and harsh environments

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 (444kHz,278kHz) and power consumption (15.58µW,32.95µW).
