这个问题的基本答案是,逻辑高表示电源轨上的电压,代表二进制 1,逻辑低表示地电压,代表二进制 0。这个描述是一个很好的起点,它变得更如果我们说“靠近电源轨”和“靠近地”而不是“在电源轨处”和“在地”,那么是准确的。此修改考虑了流过 NMOS 或 ...
在过去的 50 年中,影响最深远的技术成就可能是晶体管一如既往地稳步向更小迈进,使它们更紧密地结合在一起,并降低了它们的功耗。然而,自从 20 多年前笔者在英特尔开始职业生涯以来,我们就一直在听到警报——晶体管下降到无穷小的状态即将结束。
Since CMOS has been around for about 50 years, a comprehensive history would be a book. This blog focuses on what I consider the major transitions. Before CMOS, there was NMOS (also PMOS, but I have ...
As the people know PMOS and NMOS technology having many drawbacks. In this having speed is very slow and circuit complexity is increased and power dissipation is very high and low noise margin. So the ...
本文将介绍CMOS反相器电路中的动态和静态功耗。 CMOS反相器的发展为集成电路提供了必要的功能,是技术史上的一个转折点。该逻辑电路突出了 CMOS 独特的电气特性,非常适合高密度、高性能数字系统。 CMOS 的优势之一是其效率。CMOS 逻辑仅在改变状态时才需要 ...
Designers of electronics and communications systems are constantly faced with the challenge of integrating greater functionality on less silicon area. Many of the system blocks – such as power ...
