# NMOS/PMOS Saturation

If I recall correctly, saturation occurs if $$\V_{GS}>V_{TH}\$$ and $$\V_{DS}>V_{Dsat}\$$ for NMOS. But is there an upper limit for the voltage? Like, when does a transistor not saturate after continually increasing $$\V_{GS}\$$?

For NMOS, the conditions $$\V_{GS}>V_{TH}\$$ and $$\V_{DS}>V_{GS}-V_{TH}\$$ ensure saturation.
So an NMOS in saturation can come out of saturation if the applied $$\V_{GS}\$$ is increased beyond $$\V_{GS}=V_{DS}+V_{TH}\$$.
