Please tell me how does the vds affect gm/id plots? Will I get the same gm/id plot if I use a vds of 0.9 and 1.8 volts? In a practical circuit different transistors have different vds valus right?
As mentioned in the lecture, to be exact, the characterization has to be done for different values of Vds and Vbs. The corresponding set of data has to be used while sizing.
gm is proportional to the square root of width while Id is proportional to width. How is gm/id independent of width. If I follow your reasoning it should also be independent of length?
thanks

yes. gm/Id is independent of technology node
