Abstract :
A measurement procedure is developed specifically to characterize the phase noise of low Q, relatively unstable free-running oscillators. The phase noise performance of a VCO is evaluated theoretically using nonlinear computer aided design (CAD) tool and experimentally using phase noise measurement system. General procedure and equipment setup is introduced. Effect of power supply on the phase noise is illustrated
