Dynamic offset comparator

WebJul 1, 2024 · The standard technique for comparator offset simulation is to use a rising ramp (stair-case) input signal and detect the output transition [ 8, 9 ]. The input voltage at which the output performs a low-to-high transition is Vos in the rising direction ( Vos,R ). Next, a falling ramp is applied, where the input voltage at which the output ...
