在电路中，NMOS经常用作下管，S极接地，用G极来控制管子的导通截止，很方便。 NMOS用作上管时，因为S极电平不确定，即G极电平也不好确定，很不方便。 PMOS经常用作上管，S极接固定的VCC，用G极来控制管子的导通截止。 用作下管时，因为S极电源不确定，无法 ...

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 ...

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 ...

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 ...

X-Fab Silicon Foundries has added 375V power transistors to the devices available from its 180nm deep trench isolation BCD-on-SoI platform chip fab. The second generation of its XT018 super-junction ...

The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
