Abstract

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
