CODE MAPPING METHOD APPLIED TO DIGITAL-TO ANALOG CONVERTER

摘要

A code mapping method includes: providing M bits of digital input codes; checking the 1st bit of the M bits to generate a checking result; determining whether to perform 2's compliment operation on the 2nd to Mth bits according to the checking result; and converting the 1st to Nth bits of the M bits into P bits according to a designated mapping manner.
