By S. Pérez, D. Floriot, PM Gutiérrez, J. Obregón and SL Delage.

The phase noise generated in the oscillator circuits constitutes one of the main problems in communication systems, so it must be minimized. This article describes the influence on the spectrum of this type of noise of the different ORD topologies and the operating point of the active device, indicating the main practical methods of designing said oscillators.
