A variable frequency oscillator, or frequency modulated oscillator, using a phase modulator and comprising amplifying means, an oscillating circuit and variable phase change means coupled in a regenerative loop in such a way that a variation of said phase change it produces a corresponding change in the frequency of the signals of said oscillating circuit, characterized in that it includes means for comparing the sum and the difference between a modulation control signal and the signal produced by said oscillating circuit with a fixed reference signal.
