I don't agree to this reasoning,
A sigma delta converter is different to how one might expect that they work.
The sigma part is an intergration point of the converter. This is used to
only reduce the delta of the incomming signal so that a simple comparator
can be used in the desission process (Have a look at stuff on one bit DSP).
The great thing about this style of converter is that the noise is high pass
filtered by nature of design. The basic concept of sigma (intregation) delta
(Change in) has been around since the 1950's but only in recent times has it
been of use.
