A new scheme for reducing the phase‐modulated (PM) noise of an oscillator from correlation between amplitude‐modulated (AM) and PM noise is presented. Experimental results of this correlation effect are also presented. An improvement of almost 10 dB in the PM noise is reported for frequency offsets with strong correlation.
