in P. V oinigescu, Senior Member , IEEE Abstract—A 75-to-91 GHz receiver front-end, consisting of a three-stage cascode low-noise amplifier (LNA), a double-balanced Gilbert-cell mixer and a differential DC-to-9 GHz IF buffer, is reported in 65-nm general purpose (GP) CMOS technology. The noise and input-impedance matched LNA employs a cascode input stage with shunt-series, transformer feedback. A theoretical and experimental comparison with a conventional inductor-feedback LNA indicates 0.5–1 dB
