摘要
本文指出了线性“与或”门与发射极功能逻辑(EFL)的联系,通过理论计算与PSPICE模拟证明了线性“与或”门的极高速工作特性和可多级级联工作能力。在对线性“与或”门所需配用的高速开关分析基础上,设计了两种ECL电路。本文还讨论了应用线性“与或”门设计超高速数字电路的准则以及有关的组合和时序电路设计实例。
The paper reveals the relation between linear AND-OR gate and the Emitter Function Logic (EFL). 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 (ECL) circuits are designed. The paper also discusses the design principle of super-high-speed digital circuits and some examples of combinational and sequential circuits using linear AND-OR gate are given.
