Abstract<\/strong><\/p>\n

Single-Electron Transistors (SETs) [1][2] are attractive candidates for post-CMOS VLSI ICs. Accurate models are also required in order to efficiently design SET circuits and hybrid circuits. We have developed a new physical compact model of SET [3][4], which enables the accurate simulation of SET circuits and hybrid circuits in a SPICE-like environment. We show advanced examples of applications of our approach: simulations of elementary circuits which functionalities have been experimentally demonstrated in the literature [5][6].<\/p>\n

1 Introduction<\/strong><\/p>\n

SETs have attracted much attention because of their low power consumption and small size [1][2][7]. Recent works [5][6] show that Single-Electron Transistors could enable innovative functionalities if they are associated with MOSFETs. However Monte-Carlo (MC) simulation [8] is not adapted to the analysis and the optimization of realistic logic circuits with a large number of devices (MOSFETs and SETs).<\/p>\n

In this paper, we propose a compact physically based SET model, describing SET characteristics accurately over a wide range of temperature and voltages [4]. Our approach is simpler and more efficient than those presented in the literature [9][10]. Our model has been validated in static and dynamic regimes [4], at both device and logic circuit levels, by comparison with the MC simulator SIMON [8].<\/p>\n

2 SET Modeling<\/strong><\/p>\n

Our model is derived on the basis of the \u201corthodox\u201d theory of single charge tunnelling and the master equation method [1][2]. The number of elementary charges e in the SET island (Figure 1.a) is supposed to be n = -1, 0 or +1. This model (detailed elsewhere [4]) is built on this assumption and the periodicity of the current IDS<\/sub>(VGS<\/sub>) : the average IDS<\/sub>\u00a0current (Figure 2.b) is determined as a function of the VDS<\/sub>\u00a0and VGS<\/sub>\u00a0voltage, the temperature and the offset charges, q0<\/sub>.<\/p>\n
