Semiconductor chip with a number of A/D converters that include a group of redundant A/D converters

摘要

The manufacturing yield of an A/D converter semiconductor chip is significantly increased by utilizing a number of A/D converter circuits that include a group of redundant A/D converter circuits. As a result, the semiconductor chip can be wired to form a "good" A/D converter semiconductor chip as long as the number of "bad" A/D converter circuits does not exceed the number of redundant A/D converter circuits.
