ATE measurement technique for comparator threshold voltage

摘要

A system and a method for testing a comparator include generating two triangular waveform segments having the same period and different amplitudes, inputting the two triangular waveform segments into a comparator, receiving an output of the comparator, and calculating threshold voltages of the comparator based on the output. A periodic waveform can also be generated with repeating triangular waveform segments having the same period and different amplitudes as input to the comparator.
