Abstract

The values X(n) input to a current-steering digital-to-analog converter (49) are modified (41) before the actual conversion to compensate for conversion errors of the digital-to-analog converter. The input values are modified according to a model (43) of the digital-to-analog converter in which each output value of the digital-to-analog converter Y(n) is a sum of a desired value directly proportional to the respective input value and an error. The error is a product of the settled output value, i.e. the difference between the desired value and the previous output value Y(n-1) actually provided by the digital-to-analog converter, and a relative step error that is a function only of the respective input signal and is stored in a table. The relative step error can be a function also of the previous output signal and of the previous input signal. This model has a low complexity and is suitable for on-chip implementation.
