# Thermal noise driven computing

@article{Kish2006ThermalND, title={Thermal noise driven computing}, author={Laszlo B. Kish}, journal={Applied Physics Letters}, year={2006}, volume={89}, pages={144104} }

A new type of computing, where thermal noise is the information carrier and the clock in a computer, is proposed. The energy requirement/dissipation is studied in a simple digital system with zero threshold voltage when the thermal noise is equal to or greater than the digital signal. In a simple realization of a thermal noise driven gate, the lower limit of energy needed to generate the digital signal is ≈1.1kT∕bit. The arrangement has potentially improved energy efficiency and it is free of…
