Abstract
Methods, articles of manufacture and systems for the correction of static mismatch errors in D/A converters, where an input word, being the digital representation of an analog input signal, is divided into one most significant part, msb-word, and one least significant part, lsb-word, where msb-word is represented by msb-bits and lsb-word is represented by lsb-bits. Correction is performed by setting the effective weight of the least significant msb-bit to be less than the total sum of all lsb-bits, implementing a first look up table, LUT, containing the most significant part of the error, so that a corrected msb-word, c-msb-word, would be equal to the msb-word plus a value in LUTrepresenting the msb-word, and implementing a second look up table, LUT, containing the least significant part of the error, so that a first corrected output, c1-output, would be equal to c-msb-word plus a value in LUTrepresenting the c-msb-word added to the lsb-word.
