  • Patent number: 10361731
    Abstract: A Delta-Sigma modulator architecture is disclosed that uses interleaving and dynamic matching algorithms to address the needs of multi-mode, multi-band high bandwidth transmitters. The proposed architecture also supports a novel software defined transmitter architecture based on an interleaved Delta-Sigma modulator to generate RF signals. The proposed architecture leverages interleaving concepts to relax subcomponent clock rates without changing the effective oversampling ratio, thus, making it easier to reach aggressive dynamic range goals across wider bandwidths at higher frequencies. The DEM algorithm helps to randomize mismatch errors across all interleaved paths and improves substantially the signal-to-noise ratio. Additionally, a tunable bandpass filter can be added to reject out-of-band emissions.
