摘要
根据电流信号易于实现算术运算的特点,定义了阈算术运算、非负运算和阈算术函数,提出了和图为阈算术函数的图形表示,从而建立了阈算术代数系统.并通过具体的电流型CMOS电路的设计实例,阐述了算术意义明确的电流型电路设计方法及基于和图的电流型电路设计方法,实现了阈算术代数在二值电流型CMOS电路中的应用.计算机模拟结果表明,所设计的电路具有正确的逻辑.提出的阈算术代数系统为电流型电路的设计提供了一种新的简单有效的方法.
Based on the characteristics of current-mode circuits, which can easily realize arithmetic operations, the threshold-arithmetic operation, nonnegative operation and threshold arithmetic function are defined in this paper, Besides, HE map is defined and used as the graphic representation of threshold-arithmetic functions. Then the threshold arithmetic algebraic system suitable to design current-mode circuits is established. With current-mode CMOS circuits design examples, the design methods for current-mode CMOS circuits are expounded. The simulation results show that the designed circuits have the correct functions. The threshold-arithmetic algebraic system is a new effective method for designing the current-mode circuits.
