Design and chip fabrication results for complementary RF circuit topologies that utilize the complementary RF characteristics of both NMOS and PMOS field-effect-transistor devices combined in parallel way are reported, which can inherently provide single-ended differential signal-processing capability, requiring neither baluns, nor differential signal generating/combining circuits. The proposed complementary CMOS parallel push-pull (CCPP) amplifier gives an order of magnitude improvement in IP2 than an NMOS common-source amplifier and single-balanced CCPP resistive mixer, which functions effectively as a double-balanced one, provides more than an order of magnitude better linearity in IP2, and similar order of magnitude better local oscillator (LO)-IF and LO-RF isolations than NMOS counterparts.
