Answer:
1. Vgs<0.7
2. Vgs>2.5
3. 0.7<vgs<2.5
Explanation:
The information below was used to answer to answer this question.
Vds = 1.8V
Vt = 0.7V
1.
The cutoff region
Vgs < Vt
= Vgs < 0.7 volts
This the cut off region
2.
Linear region
Vds < Vgs - Vt
When we put in the values
1.8V < Vgs - 0.7V
1.8V+0.7V < Vgs
2.5Volts < Vgs
This is the linear region when Vgs > 2.5 volts
3.
The saturation region
Vds > Vgs - Vt
When we put in the values we have:
1.8V > Vgs - 0.7V
2.5V > Vgs
And 0.7 < Vgs
Then the saturation region is:
0.7V < Vgs < 2.5 V
