In the CMOS Op-Amp Design, it often mention that ensure MOS transistors operate far away from the subthreshold region,describe to operate the transistors wiht a minimum gate overdrive voltage. Vgs - Vt = sqrt(I*L/uCox*2W) >= Voverdrive,min
but when the current is very low,base this equ ,the W/L would be too large. so i want to know when it's low current ,how to fix the W/L?
