【摘要】 文章将讨论一种新的互补逻辑结构—互补电流镜逻辑(Complementarycurrent-mirrorlogic)。它与其它逻辑器件的区别主要是靠输入输出门之间的电流流向来确定逻辑,是一种电流型逻辑器件。本文通过PSPICE模拟来研究互补电流镜的原理、开关及连接特性。从研究结果得出互补电流镜在简单门电路下速度可与ECL电路相近,而功耗接近CMOS电路,因而互补电流镜是一种前景光明的新型逻辑结构。更多还原

【Abstract】 Recent years silicon technology have rapidly developed driven by MOS technology,especially CMOS technology.However, researchers were absent of comprehension in the progress of advanced bipolar trasistor technology.In this paper,we discussed a new bipolar transistor logic-Complementary current-mirror logic (CCML) based on PSPICE simulations.CCML primarily operated on in-out current levels,,which is significantly different from traditional methods.According to PSPICE simulation,we studied the theory、logic and joint properties of CCML.The results showed that the performance of CCML can compare with ECL circuit in terms of high speed and can compare with CMOS circuit in terms of low power dissipation. The current work provided new perspectives in this field.更多还原
