The simple 1-st order SD

Some BOEC:

With a 1st order SD the noise is going to have a 1st order highpass
spectrum, with a 1st order lowpass reconstruction filter we get a
shelving filter with flat noise spectrum.  The noise floor is then
directly proportional to the oversampling factor at the 3db point of
the lowpass filter.

I really need to simulate this..

I think I'm understimating the power of the noise.
