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