increase gm by w / l
I have known that the voltage match is better if the Vdsat is small. I will make the W/L larger to achieve it.
If i use a pair of mos whose W/L is very large and Id is very small, the mos will be in the sub threshold region. How about the voltage match of the mos differential pair in sub threshold region. Is it better than mos in saturation region?:?:
