Patent number: 10735008Abstract: A comparator offset voltage self-correction circuit is disclosed. A comparator offset voltage which is caused by the semiconductor process parameter randomness also has randomness. Due to the randomness of the comparator offset voltage, a reference voltage of a parallel comparator in a parallel-conversion-type analog-to-digital converter is uncertain.
