Abstract :
This paper provides a design methodology for a fourth order nested bus-splitting Error Feedback Modulator (EFM4) intended for an oversampled DAC application. The nested bus-splitting EFM4 runs approximately 38% faster than a conventional EFM4 on a Xilinx Virtex 5 with negligible degradation in spectral performance.
