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 has been catching up in performance, too. In fact, at 20nm the two transistor types have proven nearly equal in performance—but not for long. NMOS is about to get a big bo... » read more
