A 67 GHz 23 mW Receiver Utilizing Complementary Current Reuse Techniques

This paper presents a very low power, low noise receiver operating at V-band which is enabled by the application of ultra-low power RF design techniques in the mmWave domain. This device takes advantage of both complementary current reuse and moderate inversion biasing, combined with a compact and extremely power efficient frequency doubler, to acheive 23 mW power consumption while operating between 60 GHz and 75 GHz for an RF bandwidth of 15 GHz. The receiver achieves superior noise performance compared to other receivers operating at similar power in the same band, enabling a state-of-the-art power versus noise performance. The receiver achieves 3.6 dB of NF, -21.5 dB PldB and 15 GHz BW while consuming only 23 mW. The obtained power consumption normalized to its noise figure shows a significant improvement over existing art, making it an ideal candidate for integration into digital beamforming arrays where low power and low noise are desirable to optimize effective isotropic sensitivity under a given power constraint.
