Question

Assuming an n-type transistor with Vds of 1.8V and Vt of 0.7V, find the ranges of Vgs to put the transistor in cutoff, linear, and saturation regions.

Answer 1

1. Vgs<0.7

2. Vgs>2.5

3. 0.7<vgs<2.5

Step-by-step 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
