Wide Tuning Range and Low Noise Voltage Control Oscillators for 5G Technology
Abstract
This paper presents the analytical design of a new wide tuning range and low-noise millimeter-wave voltage control oscillators (VCO) for 5G technology. The small signal model analysis and phase noise of the VCOs will be presented to evaluate the start-up oscillation condition, oscillation frequency, and phase noise affecting factors. Theoretical analysis and simulation results show the outperformance of the proposed cascode cross-couple LC VCO topology compared to the conventional cross-coupled LC VCO in terms of frequency tuning range, VCO gain and phase noise level.
