A SPICE model for single electronics

Abstract

With single-electron tunneling (SET) technology it is possible to build electronic circuits with extreme low power properties. These SET circuits must therefore operate in the single electronics (current) regime. To simulate SET circuits in this regime, a SPICE model has been written. In contrast to the prescriptions in the so-called orthodox theory of single-electronics, the SPICE model explores the discrete character of the tunnel current and the tunnel condition. In this paper, a brief description of this SPICE model is given. Several known SET circuits are simulated using this SPICE model and are verified with a well known SET device simulator called SIMON, which is based on the orthodox theory of single-electronics.
