Hi, I know that W/L ratio changes vds,sat(= vgs-vth). Increasing/decreasing W/L decreases/increases (Vgs-Vth), but how does it change drain voltage if the drain current is constant. Also, what happens to drain voltage just by changing only W or L. For ex, W/L =10, W=10 um and L = 1 um or W= 1 um and L = 100 nm, is the drain voltage going to be same in both cases. Please also explain what happens to gate voltage and Vth. Thanks
