FM Noise Suppression of an Injection Phase-Locked Oscillator

The phenomenon of injection phase-locking may be used to synchronize one or more oscillators to a lower power master or reference oscillator and also reduce part of the resultant FM noise power spectrum. A theory is presented that predicts the resultant FM noise spectrum of an injection phase-locked...

Description
Summary:The phenomenon of injection phase-locking may be used to synchronize one or more oscillators to a lower power master or reference oscillator and also reduce part of the resultant FM noise power spectrum. A theory is presented that predicts the resultant FM noise spectrum of an injection phase-locked oscillator when the spectrum of the reference source and the free-running oscillator are known. Experiments conducted are described and comparison with theoretical predictions are discussed.
