On Power Dissipation in Information Processing

Roman Ostroumov, Kang L. Wang

Open publisher page 4 citations

Abstract

We consider power dissipation during simple switching in information processing. By considering general two-level system we show that the energy dissipation during errorless switching has a minimum of kTln2 and increases linearly with a switching speed. Also, we find optimal switching function, which minimizes heat dissipation for the given error rate. We present some estimates and compare them with results for the CMOS technology.
