Design a delta-digma DAC

hi All,
I am a newer in delta-sigma modulator design.
Can u give a suggetion how to decide the architecture of a delta-sigma
modulator for DAC? It need SNR 96dB, 24 bit input for audio signal.
I try to use Richard Sherier's matlab toolbox to design it.
But I am confused to deicde the one of them. And it don't support
Error-Feedback type.
Thanks for any response.

Best reguard,

Re: Design a delta-digma DAC

I think you can see some IEEE paper to decide it. I think you can use fifth-order single bit modulator, 64X oversampling. You can find the architecture in ‘Delta-sigma data converters --- Theory,Design,and simulation' IEEE press.
