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 ...

A key challenge to the ultra-miniaturization of electronic systems is power management. As any EE knows, when overall system sizes shrink the amount of area available for energy storage and energy ...

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 ...

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 ...

X-FAB has added three new low-noise transistors to its 180nm process node: a 1.8 V low-noise NMOS, a 3.3 V low-noise NMOS and a 3.3 V low-noise PMOS – all of which offer drastically reduced flicker ...
