Abstract: A study of a CMOS sub-sampling RF mixer,based on the Second generation switched-current track (S2I) and copy cell,is presented.The use of S2I circuits to realize highly integrated RF receivers presents some new and unique design opportunities.The paper discusses the advantages and disadvantages of the second generation S2I cells for use as a sub-sampling mixer and presents some preliminary simulation results.The results show that a S2I sub-sampling mixer is feasible and offers excellent linearity and good dynamic rang.

Key words: switched current, sub-sampling, mixer
