Electronic oscillator circuit, comprising an oscillator, for supplying an oscillation signal with an oscillation frequency dependent on a control signal, a controller for delivering the control signal as a function of a phase difference between a first controller input and a second controller input, a resonator, such as a piezo-electricoscillator, with at least one resonance frequency, and a phase shift dependent on the difference between the frequency of an exciting signal and the resonance frequency wherein the oscillation signal is fed back to the first controller input, and wherein the oscillation signal is fed back to the second controller input via the resonator.
