Abstract
A regulator for a digital-to-analog converter having in input a digital signal and suitable for providing an analog signal in output, the regulator including at least one pair of buffers having in input the digital signal and the outputs connected to a pair of circuit branches connected to the output of the regulator; each of the at least two circuit branches having at least one resistance. To at least one of the at least one pair of buffers a variable resistance is associated, and the regulator includes a circuit having in input the analog signal and adapted for measuring its waveform and acting on the variable resistance in response to its possible anomalous waveform compared to a desired waveform.
