The choice significantly impacts area, performance, and reliability. === Key Concepts === * '''Bulk (or Body):''' The underlying silicon substrate on which the transistor is built. It must be tied to a stable voltage potential (e.g., VSS for NMOS, VDD for PMOS). * '''Bulk Contact:''' The physical con..." Tag: Visual edit
