- Based on experimental results, the phase noise of offset phase locked loop (PLL) is analyzed theoretically and experimented. Analyses are developed both to calculate the in-band phase noise of a given synthesizer architecture and to predict the impact from the the phase noise of offset local oscillator (LO). This article verifies that the phase noise of offset LO give a direct impact on the in-band phase noise of frequency synthesizer. © 2013 Wiley Periodicals, Inc.
