NMOS在实际应用中为何比PMOS要更受欢迎，本文将从导电沟道、电子迁移率和器件速度等多个方面来展开讲解。 首先是在性能 ...

在性能相当的条件下，一颗 PMOS 管的器件面积通常需要达到 NMOS 管的 2~3 倍。更大的面积不仅影响芯片的集成度，也会带来更高的导通电阻和输入输出电容，进而增加电路延迟。 与此同时，若尺寸相同，PMOS 的沟道导通电阻一般大于 NMOS，因此其开关过程中的导通 ...

Even as industry moves into the era of the high k metal gate (HKMG) and FinFET transistor, chipmakers continue to seek ways to improve device performance. One of the latest advances and the subject of ...

When a CMOS circuit is in an idle state there is still some static power dissipation–a result of leakage current through nominally off transistors. Both nMOS and pMOS transistors used in CMOS logic ...

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 ...

For years—decades, in fact—the NMOS transistor world has been on cruise control. NMOS is naturally faster and its performance has scaled better than PMOS. PMOS has had a cost advantage. But lately, it ...

PMOS transistors are less vulnerable to substrate noise since they’re placed in separate wells; designers implement guard rings to attenuate the substrate noise propagation. However, substrate noise ...

Intel is in production with several 65-nm processors now, creating an inventory of commercial microprocessor products that will begin shipping early next year. At the IEDM conference, Intel showed die ...

Moore’s Law has been the guiding principle for the semiconductor industry for more than fifty years. For thirty of those years, I have had the privilege of working in Intel’s technology development ...
