ABSTRACT:
A method and apparatus for correcting errors in a thermometer code data array (32). A parallel A/D converter (22) comprises an array (26) of comparators and an encoder (30). The correction of errors in the data array (32) produced by the comparators (26) is accomplished by an array (24) of majority error correction gates which is placed between the array (26) of comparators and the encoder (30) in the A/D converter (22).
