Claim of US Patent No. 10,367,522

1. A parallel delta sigma modulator comprising:a signal demultiplexer configured to receive an input signal and to demultiplex the input signal into a plurality of streams of symbols at symbol boundaries;
a plurality of delta sigma modulators, where each delta sigma modulator is configured to receive a stream of symbols from the plurality of streams of symbols and to generate a delta sigma modulated output; and
a signal multiplexer configured to receive a plurality of delta sigma modulated outputs from the plurality of delta sigma modulators and to multiplex together the plurality of delta sigma modulated outputs into a pulse train; and
a frequency up-converter configured to receive the pulse train.
