Can somebody reference me publications showing the design of ADC (pipeline or SAR) working in sub-sampling mode (IF subsampling in wireless receivers), whereas the ADCs has larger analog input bandwidth then its own sample-rate, this means, the ADC works in higher Nyquist bands (>10).
I found the IEEE SSC Publications of Ahmed Ali (ADI, NC) showing a 14b pipeline ADC with 125MS/s with up to 500MHz BW (8th Nyquist band) from JSSC 2006 and a 16b pipeline ADC with 250MS/s with 300MHz analog-BW (3rd Nyquist band).
And some 10b pipeline ADCs from China: Jian Li (JSSC 2008) with 30MS/s with BW=30MHz (2nd Nyquist Band) and Chen Lijie (2010) with 50MS/s with BW=50MHz (2nd Nyquist Band).
Subsampling operation SAR ADCs I found only two: Shuo-Wei Michael Chen (UC Berkeley) from JSSC 2006 with 6b 600MS/s SAR with BW=4GHz (13th Nyquist Band) and Michael Trakimas (Tufts Univ, MA) with 10b 10MS/s SAR with BW=25MHz (5th Nyquist band) from 2013 (IEEE CaS-I.).
Can somebody advice me some more subsampling-mode (IF sub-sampling) ADC from the literature?
Thank you in advance.

There's a lot of such ADCs available. Just have a look at some major manufacturers:
http://www.ti.com/lsds/ti/data-converters/adcs/high-speed-adcs-products.page#p157max=300;1400
http://www.analog.com/en/products/analog-to-digital-converters/high-speed-ad-10msps.html (sorry - they don't have the BW in this table)
https://para.maximintegrated.com/search.mvp?fam=fast_adc&717=125
and so on. An input bandwidth beyond Nyquist does not necessarily address subsampling (though making it possible) - it may as well support input multiplex or improved performance (then relying on some low-pass + buffer in the input signal path).

Refer to some Application notes and the ADC parts mentioned therein from Analog Devices. They have very good collection of technical information which will help you precisely.
Thanks and best regards,
