Homework Statement


Just started learning about transistors, and I am having difficulty doing this problem.

The transistor in the circuit has [tex]k_n ^'=0.5mA/V^2, V_t=0.5 V, \lambda =0.[/tex]
Show that operation at the edge of saturation is obtained when the following condition is satisfied
[tex](\frac{W}{L})R_D=1.5 kΩ[/tex]


The Attempt at a Solution


As far as I know, if it is operating in on the edge of saturation, then
[tex]\frac{1}{2}k_m ^'(\frac{W}{L})v_{OV}[/tex]
However, when I manipulate this equation, I am unable to get to [tex](\frac{W}{L})R_D=1.5 kΩ[/tex]

Can anyone provide me some guidance on this?

Thanks anyways, but I figured it out.

Hi, I'm bumping this old post because I am currently trying to work through the same problem but can't quite figure it out. I have the same equations that were mentioned in the original post.

Any guidance would be appreciated.
