• A supply-voltage scalable, low-power, millimeter-wave UWB receiver fabricated in 45nm SOI CMOS is presented. All stages in the LNA and the quadrature mixers are limited to a single transistor in the stack between supply and ground, thereby allowing supply voltage scalability. A transformer neutralization technique is introduced for CG and CS stages to mitigate the deleterious effect of reverse signal flow. This ensures stable, unilateral operation over the entire bandwidth. The receiver achieves 46-64 GHz (48-68 GHz) bandwidth, 24.5 dB (20.7 dB) conversion gain, 5.3 dB (7.8 dB) NF and -22 dBm (-21.7 dBm) P1dB from a 1.1 V (0.6 V) supply voltage while consuming 18.4 mW (7 mW) power.
