Dirt Cheap ASIC Design for Dummies (Part 3): NMOS, PMOS Silicon Design Using a Web Browser

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 ...

Use Hybrid PMOS-NMOS Active Loads To Cut Substrate Noise In Differential Amplifiers

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 ...

Speeding Up NMOS

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 ...

An introduction to semiconductor technologies for power management – Part 2

N-MOS and P-MOS transistors are analogous respectively to NPN and PNP transistors but their conduction mechanism is based completely on one type of carrier: holes for the PMOS and electrons for the ...
