Hello,
i m getting difficulty in realizing that,How operating region of nMOS and pMOS is decided based on output voltage levels ?
like for nMOS vout<vdd+vt then it's saturation ans so on..
The operating region of Pmos/Nmos depend only [Vgs - Vt] and Vds, and you wonder about Vout ( you should consider where you take Vout to ensure the region you want to control).
Regard.
