Specifically, I'm building a constant-gm bias circuit (ie. delta-Vgs) with relatively low current consumption. What are the drawbacks of operating in subthreshold vs saturation?
I know it will cost me more area to bring the operation to subthreshold (i.e. high W/L) but how about performance drawbacks, are there any?
Mismatch effect is greater in subthreshold?
Thanks in advance for your replies.
