THE NEW SUPER-HIGH-SPEED DIGITAL CIRCUIT BASED ON LINEAR AND-OR GATES

The paper reveals the relation between the linear AND-OR gate and the emitter function logic. With theoretic calculation and PSPICE simulation, the paper proves that the linear AND-OR gates can work at super-high-speed and can be multi-cascaded. On the basis of analyzing the high-speed switch units which coordinate with linear AND-OR gates, two kinds of emitter coupled logic circuits are designed. The paper also discusses the design principles of super-high-speed digital circuits, and some examples of combinational and sequential circuits using linear AND-OR gate are given.     

对基于模代数的三值触发器的研究

本文用模代数讨论三值触发器。提出了基于模代数的三值 JK 触发器。与基于 Post代数的三值 JK 触发器相比,它的逻辑功能是均衡的,它能像二值 JK 触发器一样方便地构成另外二种常用的触发器:三值 D 型触发器与三值 T 型触发器。此外,由时序电路的设计实例,也证实了因它的功能较强而能导致较简单的激励函数与组合电路。     

Power Minimization of FPRM Functions Based on Polarity Conversion

For an n-variable Boolean function,there are 2^n fixed polarity Reed -Muler(FPRM)forms.In this paper,a frame of power dissipation estimation for FPRM functions is presented and the polarity conversion is introduced to minimize the power for FPRM functions.Based on searching the best polarity for low power dissipation,an optimal algorithm is proposed and implemented in C.The algorithm is tested on seven single output functions from MCNC benchmark circuits.The experimenta results are shown in this paper.
