Hi all,
this is a paper recommended by another member
Quote:See paper on ZigBee Transceiver which is zero-IF architecture by ADI in ISSCC-2009.
[24.4] "A Highly Integrated Low-Power 2.4GHz Transceiver Using a Direct-Conversion Diversity Receiver in 0.18um CMOS for IEEE802.15.4 WPAN"

I personally haven't read the paper as it hasn't yet been uploaded to IEEE xplore but if you can get your hands on it, I think it is very relevant (not actually low-IF but does use sigma delta).
cheers,
