WebSection 3 details why most comparators in supervisory circuits use the active pullup topology. This topology has a large impact on the system, specifically on how supply current and propagation delay is effected. The effect of comparator architecture is most evident in window comparators where there are both overvoltage and undervoltage thresholds. WebFig. 3 describes how the proposed method can be applied to measure the ISF in the lab. As in the simulation, a small step whose edge is spaced from the clock edge by τ is applied to the comparator input and the step’s offset voltage VOS is swept until the value that makes the comparator metastable is found, i.e. VMS(τ).
