This article describes a substrate voltage sensitivity detector which detects the sensitivity of thresholds as a function of source-to-substrate voltage, and yields its slope. Let WLL = width-to-length ratio of L WLA = width-to-length ratio of A WT = threshold voltage for a ground source device M = slope of change of VT as a function of source voltage change The following equation applies: WLA /2 (Vo-VT)/2/ = WLL /2 (V-(1 m) Vo-VT)/2/
