Supply Noise Effect on Oscillator Phase Noise

Texas Instruments

Published Date: 11/22/2011

Description

This report provides the description of local oscillator (LO) phase noise degradation due to supply noise. Brief theoretical information supported by experiments carried out to demonstrate this degradation is discussed. The importance of selecting appropriate low-noise LDO (low-dropout) linear regulators is discussed. The impact of improper LDO within in-band phase noise of a multi-GHz synthesizer
