Average bubble correction circuit

摘要

The present invention is to provide an average bubble correction circuit which will expand the range of bubble error correction and will detect the proper position of the 1/0 state-conversion points of the thermometer codes to low down the error rate that caused by the ROM decoding. The average bubble correction circuit is used in the analog to digital converter and will convert the thermometer code obtained from the comparator of the analog to digital converter into the 1/0 state-conversion point.
