  • Radio frequency amplifier
    Patent number: 10686417
    Abstract: A modulator circuit includes a plurality of signal processing branches, each branch having a modulator for performing a delta-sigma modulation of a respective data stream portion in order to generate a modulated signal. The modulator circuit receives an input data stream having a carrier frequency; splits the input data stream into a plurality of data stream portions. Delta-sigma modulation is performed in each branch on a respective data stream portion. The respective modulated signals from each branch are combined to form an output signal for outputting at the carrier frequency.
