Abstract
A current steering digital-analog converter for converting a digital code into an analog signal, the converter including a substrate of semiconductor material, an array of current generators integrated in the substrate, a common summation node and switches controllable on the basis of the digital code for connecting and disconnecting the current generators to and from the common summation node. The current generators are adapted to provide the common summation node with currents having a multiple value according to a power of two compared to a unit current value provided to the summation node by a current generator of the array of generators. The current generator is divided into a base number of modular current generation elements in parallel to one another at least equal to two.
