Abstract
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.
Claims19
An average bubble correction circuit receiving a plurality of the thermometer codes in order to correct the bubble, and comprising at least one bubble correction cell in which the adjacent 2m+1 thermometer codes are selected from a plurality of the thermometer codes, and detecting the most occurrence amount of the states of the 2m+1 thermometer codes, and outputting a distinguishing code.
An average bubble correction circuit receiving a plurality of the thermometer codes to correct the bubble error and comprising at least a bubble correction cell in which the adjacent five thermometer codes are selected from said plurality of the thermometer codes, detecting the state of the most occurred of the five thermometer codes, and outputting a distinguishing code according to the state of the most occurred bubbles.
An average bubble correction circuit which receives a plurality of the thermometer codes, comprising:
