WebMar 19, 2024 · The majority of modern bulk CMOS processes (>180nm) have NMOS body connections directly to the p-substrate of the wafer, meaning there's only one, common substrate node for every N-type FET in the IC. PMOS devices are laid out in separate n-wells which allows distinct body connections. WebIn a PMOS transistor if the source terminal is at a lower potential compared with the body, the transistor has body-effect and the threshold increases. If the source terminal is at a …
