“…A Monte Carlo simulation is performed; the noise is added in the time domain and weighted appropriately. The results are compared to the expected value of the phase noise derived using the approach from [1] and [5]. The total power consumption of the oscillator is improved from 40.8 mW to 4.8 mW.…”

“…A key characteristic that defines the performance of an oscillator is the phase noise measurement and extensive work has been done to quantify phase noise. The VCO is also a key component in phase-locked loops and will contribute to most of the out-of-band phase noise, as well as a significant portion of inband noise [5]. Current state-of-the-art modulation techniques, implemented at 60 GHz, such as quadrature amplitude modulation and orthogonal frequency domain multiplexing, require phase noise specifications better than 90 dBc/Hz at a 1 MHz offset [6].…”

This paper investigates the factors that influence the phase noise performance of an oscillator and proposes a modified structure for improved phase noise performance. A single and multiphase oscillator analysis using the harmonic balance method is presented. The modified structure increases the oscillation amplitude without increasing the bias current and leads to improved phase noise performance as well as decreased power consumption. The modification is analyzed and the figure of merit of the oscillator shows a significant improvement of 21 dB. Numerical and analytical solutions are presented to predict the oscillation frequency and phase noise. The analytical solution is used to approximate the first harmonic and can be combined with numerical simulations to extrapolate phase noise performance.
