Abstract

A 65 nm CMOS sliding-IF receiver comprising 3 LNA gain stages, RF mixer, quadrature IF mixers, VCO and dividers is presented. Coupled resonators, both in the LNA and RF mixer, allow an important gain-bandwidth extension over conventional single LC neutralization. Realized prototypes show >13 GHz RF bandwidth around 60 GHz, <6.5 dB NF, -21 dBm P_1dB, 12.6% VCO frequency range, and -115 dBc/Hz phase noise at 10 MHz offset from the carrier while drawing 75 mW.
