Performance and Trends in Millimetre-Wave CMOS Oscillators for Emerging Wireless Applications

[摘要] This paper reports the latest advances on millimeter-wave CMOS voltage-controlled oscillators (VCOs). Current state-of-the-art implementations are reviewed, and their performances are compared in terms of phase noise and figure of merit. Low power and low phase noise LC-VCO and ring oscillator designs are analyzed and discussed. Design and performance trends over the last decade are provided and discussed. The paper shows how for the higher range of millimeter-waves (>60 GHz) the performances of ring oscillators become comparable with those of LC-VCOs.
