Patent ID: 7675449

Claim:
A current steering digital-analog converter for converting a digital code into an analog signal, the digital-analog converter comprising: a substrate of semiconductor material; an array of current generators integrated in said substrate; a common summation node and switching means controllable on the basis of said digital code for connecting and disconnecting said current generators to and from, respectively, said common summation node; the current generators 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 said summation node by a first current generator of said array of generators, said first current generator divided into a base number of modular current generation elements in parallel to one another at least equal to two, each of the remaining current generators of said array of current generators comprising a number of modular current generation elements coupled parallel to one another and equal in number to a multiple according to a power of two of said base number.
