Classification of Error Correction Methods, a Broad View

This chapter introduces a classification of DAC correction methods. A set of representative DAC correction methods is selected and three fundamental groups of methods are defined: Error-Transfer-Function-Prevention (ETFP), Error-Transfer-Function-Correction (ETFC), and Signal-Transfer-Function-Compensation (STFC). Then, three categories with dichotomous classes are defined along three different angles of incidence: error measurement, redundancy, and system level. The presented DAC correction methods are ordered and the missing methods are identified. Common properties of the methods that belong to the same classes are discussed. Clues are provided for the development of new correction methods that can fill-in the gaps. A discussion about the relevance of the introduced classification is provided and potential extensions of the classification are outlined.
