A Low-Noise Fractional-N Digital Frequency Synthesizer With Implicit Frequency Tripling for mm-Wave Applications

In this paper, we propose a 60-GHz fractional-N digital frequency synthesizer aimed at reducing its phase noise (PN) at both the flicker (1/f ³ ) and thermal (1/f ² ) regions while minimizing its power consumption. The digitally controlled oscillator (DCO) fundamentally resonates at 20 GHz and co-generates a strong...

Uniform Gain Beamforming in 60 GHz Communications

Wireless data traffic is growing rapidly as the number of mobile devices increase and video contents become more popular.
