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 ...

Power dissipation in portables: Design considerations using low-power CMOS ICs

When a CMOS circuit is in an idle state there is still some static power dissipation–a result of leakage current through nominally off transistors. Both nMOS and pMOS transistors used in CMOS logic ...

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 ...

BCD Technology: A Unified Approach to Analog, Digital, and Power Design

Since its inception, BCD technology has leveraged the integration of two primary technologies—polysilicon gate CMOS and DMOS power architecture—on the same chip. Its compatibility with bipolar ...

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 ...
