In this paper the high immunity to electromagnetic interference (EMI) of complementary differential pairs is highlighted. Furthermore, a new complementary differential pair with a particularly high immunity to radio frequency interference (RFI) is presented. The operation principle of this new structure is described and design criteria are provided. Such a structure has been designed and employed as an input stage of a folded cascode operational amplifier and its reduced susceptibility to RF interference has been verified by computer simulation.
