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 ...
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 ...
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 ...
