A device for processing digital signals is provided. The device comprises a digital signal source and a converter circuit having a current supply. The digital signal source outputs a codeword. The converter circuit receives the codeword from the digital signal source, receives a current at the current supply, and generates an output signal based on the codeword. The current is generated in accordance with the codeword.

Device and method for processing digital signals

The present invention provides a device for processing digital signals. The device comprises a digital signal source configured to output codewords, a converter circuit configured to generate an output signal based on a first codeword received from the digital signal source, and a feed forward circuit configured to generate an output current based on a second codeword received from the digital signal source. The output current generated by the feed forward circuit is connected to a current supply of the converter circuit. The digital signal source is configured to generate the second codeword based on the first codeword in order to compensate for variations of a supply current of the converter circuit.
