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 ...

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 ...

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 ...

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 ...

Low-dropout regulators, commonly known as LDOs, are used extensively in a wide variety of electronic applications across many different industries. An LDO is generally perceived as a simple and ...

As you probably know, processors – and most other digital technology – are made up of transistors. The simplest way to think of a transistor is as a controllable switch with three pins. When the gate ...
