Minimizing power consumption is vitally important in embedded system design; power consumption determines battery lifespan. Ultralow-power designs may even permit embedded systems to operate without batteries, e.g., by scavenging energy from the environment. Moreover, managing power dissipation is now a key factor in integrated circuit packaging and cooling. As a result, embedded system price, size, weight, and reliability are all strongly dependent on power dissipation. Recent developments in nanoscale devices open new alternatives for low-power embedded system design. Among these, Single-Electron Tunneling transistors (SETs) hold the promise of achieving the lowest power consumption.
