Abstract
An electronic device for digital to analog conversion is proposed. Such device implements a finite impulse response filter and includes: a delay line taking as an input a digital input stream and implementing a number of successive delay cells, each delay cell outputting a corresponding delayed version of the digital input stream to be processed by a corresponding coefficient of the filter; for at least one coefficient of the finite impulse response filter, a number of positive current sources, contributing to a positive current component of a differential analog output of the device and negative current sources, contributing to a negative current component of the differential analog output. The current component contribution of the positive and negative current sources are reconfigurable between predetermined values for allowing the value of the coefficient to be reconfigurable.
