Experimental validation of DAC with nested bus-splitting EFM4 DDSM

This paper presents measured results for a fourth order nested bus-splitting Error Feedback Modulator (EFM4) with dynamic element matching and a four-bit DAC. The nested bus-splitting EFM4 can run approximately 38% faster than a conventional EFM4 on a Xilinx Virtex 5, with negligible degradation in spectral performance.
