I'm trying to solve for the minimum v(adsbygoogle = window.adsbygoogle || []).push({}); _{IN}such that MOSFET is in the saturation region. Here are the given parameters

V_{S+}= 1.0 V

V_{S-}= - 1.0 V

V_{T}= 0.5 V

In order to enter saturation I know that V_{DS}> V_{GS}- V_{T}

V_{GS}= V_{IN}- V_{S-}

V_{DS}= V_{s+}- V_{s-}, which is 2 V

Which means

2V > V_{IN}- V_{S-}- V_{T}

2V > V_{IN}- (- 1.0 V) - 0.5 V

2V > V_{IN}+ 0.5 V

I get a V_{IN}of 1.5 Volts. The correct answer is -0.5 V.

I'm just starting to learn electrical engineering and it would be great if someone can point out what's missing.
