摘　　要：基于单电子晶体管(SET)的库仑振荡效应、多栅输入特性和相移特性,实现了SET/MOS混合结构的或门逻辑,并利用该或门逻辑实现了4-2编码器。利用HSPICE对所设计电路进行仿真验证,仿真结果表明该电路能够实现4-2编码器的编码功能。与纯CMOS编码器相比,该SET/MOS混合电路仅由2个PMOS管、2个NMOS管和2个SET构成,具有结构简单、尺寸小、集成度高的优点。Based on the characteristics of Coulomb oscillation,multi-gate inputs,and phase-shift of single-electron transistor（SET）,a two inputs hybrid SET/MOS OR logic gate was realized.The OR logic gate was used to construct the proposed 4-2 encoder.The accuracy of the 4-2 encoder circuit was validated by HSPICE simulation.Compared to the pure CMOS encoder circuit,the proposed circuit merely consists of two PMOS transistors,two NMOS transistors,and two SETs,which has advantages of simpler device structure,smaller size,and higher integration density.
