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 ...

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 ...

The History Of CMOS

Since CMOS has been around for about 50 years, a comprehensive history would be a book. This blog focuses on what I consider the major transitions. Before CMOS, there was NMOS (also PMOS, but I have ...

Simulating High-Side Bootstrap Circuits With LTSpice

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 ...
