ALL,
I meet a puzzle problem. In voltage follower design, I find many transistors in threshold region and the performance is good for large power supply variation. According to the general rule, the transistors should be in active region. I get the result that the performance is better while the transistor in subthreshold than that in active with the large power supply variation after I try many times.
maybe there is some magic. Please give me some pieces of advice on the problem.
Or someone can upload some design material about subthresold circuit design in CMOS process.
Is the subthresold circuit design is popular now in commercial CMOS IC design.
ALso, Is the subthreshold circuit robust while the power supply varies widely.
