Chapter 16, Problem 16.23P

In the NMOS circuit in Figure P16.23, the transistor parameters are: ${\left(W/L\right)}_X={\left(W/L\right)}_Y=4$ , ${\left(W/L\right)}_L=1$ , $V_{TNX}=V_{TNY}=0.8\text{V}$ , and $V_{TNL}=-1.5\text{V}$ . (a) Determine ${\upsilon }_O$ when ${\upsilon }_X={\upsilon }_Y=5\text{V}$ . (b) What are the values of ${\upsilon }_{GSX},{\upsilon }_{GSY},{\upsilon }_{DSX}$ , and ${\upsilon }_{DSY}$ ? Repeat part (a) for $\gamma =0.5$ .
