摘　　要：电流型电路具有高速、低功耗、带宽、设计方便、直观、易于实现多值逻辑电路等优点。阈算术代数系统的提出为电流型电路的设计提供了更符合电流信号运算特点的系统方法,而和图是将逻辑函数转化为阈算术函数的图形表示方法。本文在谱技术的基础上,提出了一种新的和图与谱系数图的转换方法,设计了一种基于和图的电流型CMOS三变量通用逻辑门,即三变量特征阈值逻辑门,可实现任意的三变量阈值函数。Current-mode circuit has the advantages of high speed,low power consumption,wide bandwidth and easiness of realizing multi-value logic circuit.The design of the threshold-arithmetic algebraic system provides a systematic method for the design of current-mode circuit which accords with the operation characteristics of the current signal.HE map is a graphical representation of which transforms the logic function to the threshold arithmetic function,it is convenient and intuitive to use the map in the process of designing the current circuit.In this paper,based on the spectral technology,we present a new method to transform the HE map and spectral coefficient graph to design a three-variable universal logic gates:three-variable feature threshold logic gates about current-mode CMOS which realizes arbitrary three-variable threshold function.
