中文摘要:
      单双稳态转换逻辑单元(MOBILE)是基于共振隧穿二极管(RTD)电路的一个重要逻辑单元,非常适合阈值逻辑电路设计。由MOBILE可以构成阈值逻辑门(TG)和广义阈值逻辑门(GTG)等阈值逻辑电路。本文通过将三变量异或函数转化为较简单、理想的GTG输入输出函数形式,设计了由GTG构成的新型三变量异或门,并利用该三变量异或门设计了新型的全加器。通过HSPICE仿真和性能比较,该全加器不仅器件数量少,输出延时短,而且能达到较高的工作频率、更小的电路功耗与功耗-延迟积。
英文摘要:
      The MOnostable-BIstable transition Logic Element(MOBILE) is an important logic unit based on Resonant Tunneling Diode(RTD) circuits, which is very suitable for the design of threshold logic circuit. Threshold circuits such as Threshold Gate(TG), Generalized Threshold Gate(GTG) and etc., can be constructed by MOBILE. In this paper, a novel three-variable XOR gate composed of GTG is designed, through transforming the three-variable XOR function into a more simple and ideal form of GTG input/output function. And a novel full-adder is designed by using the three-variable XOR gate. Through HSPICE simulation and performance comparison, the full-adder has less devices, shorter delay-time, higher operating frequency, lower power consumption and lower power-delay product.
