Single-ended differential amplifier and mixer circuits utilizing complementary RF characteristics of both NMOS and PMOS

Design and fabrication results for single-ended differential circuit topologies that utilize the complementary RF characteristic of both NMOS and PMOS are reported. The complementary CMOS parallel push-pull amplifier gives an order of magnitude improvement in IP₂ at similar power consumption, and single-balanced complementary resistive mixer that functions effectively as double-balanced one, improves similar order of magnitude better in IP₂, LO-to-IF and LO-to-RF isolations than NMOS counterparts.
