Complementary Metal-Oxide-Semiconductor (CMOS) technology is a vital part of modern electronics, used in designing and manufacturing integrated circuits (ICs) that power many digital devices. CMOS ...

Quickly learn what the difference is between PMOS and NMOS transistors in their structure and operation, and how CMOS works with the two in combination. Siliwiz, a free, browser-based, ASIC layout ...

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 ...

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 ...

LTSpice is a tool that every electronics nerd should have at least a basic knowledge of. Those of us who work professionally in the analog and power worlds rely heavily on the validity of our ...

This is the third installment in our CPU design series. In Part 1, we covered computer architecture and how a processor works at a high level. Part 2 explored the design and implementation of ...

In our previous post Low Power LDO Design Techniques for Really Small Profile Applications, Part 1, we reviewed LDO design tradeoffs using an NMOS pass transistor. This design approach is proven good ...
