This is link to the BB paper describing out of band noise for PCM delta sigma DACS:

Notice how similar the noise curve is compared to DSD. It's because they are both based on the same underlying converter technology.

As for the noise curve and application of noise shaping on a sigma delta ADC, refer to this oldie but goodie from Analog Devices:

I think Cirrus Logic has written a really good paper too, but I'll leave it to you to search for it.
