ABSTRACT:
An arrangement provides a reduced harmonic content output signal that represents a value of a digital input signal. The arrangement includes plural storage devices 301 . . . configured to sample and store the digital input signal at different respective phases of a clock signal. The arrangement also has plural current steering digital-to-analog converters (DACs) 311 . . . configured to receive respective stored digital signals from respective ones of the plural storage devices, and to provide respective currents that represent the received stored digital signals. The arrangement also includes a combining arrangement configured to combine the currents from respective ones of the plural current steering DACs, so as to provide the reduced harmonic content output signal that represents the value of the digital input signal.
