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 ...

A schematic diagram is not a detailed blueprint of an analog circuit; instead, it’s more like architectural sketch of the circuit. Look at any schematic for a CMOS analog IC circuit and you will see ...

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 ...
