Abstract
Embodiments of the disclosure provide improved mismatch shaping for a digital to analog converter, the method including splitting an original input of a circuit into a plurality of time interleaved data streams; element rotation selection (ERS) logic to process the plurality of time interleaved data streams; and directing one of the plurality of time interleaved data streams to the ERS logic according to a decision of a data-weighted sigma-delta (SD) modulator. In other example implementations, the method can further include multiplexing one of the plurality of time interleaved data streams to be provided to a barrel shifter. In yet other examples, the method can include monitoring a difference between the plurality of time interleaved data streams as a basis for the directing such that a data sample rate for the digital to analog converter is reduced over a time interval.
