I have simulated a StrongArm comparator which its inputs are beyond its supply (for instance: Vdd=0.9, Vi+=1.35+0.45*sinwt, Vi-=1.35) and surprisingly it works properly (even in the simulation corners). If it is so, why don't we decrease the supply to save power, what is wrong with decreasing the supply as much as possible for any input range?
Thanks in advance Thanks, so there will be no problem if one wants to fabricate this circuit? Since I have heard about issues including : "bulk current" (which I have checked in the simulations and it was OK) or "latch up" or " oxide stress" which Daniel mentioned?
