The oscillator (1) of integrated monolithic design has several analogue amplifier units (2) connected in a ring. The individual amplifiers are frequency selective in regard to a resonance frequency. The phase displacements of the amplifiers are chosen so that the total phase displacement over the ring at the resonance frequencies of the amplifiers amounts to 3600 or a whole number multiple of that. The number of amplifiers selected corresponds to the overall quality factor for the ring oscillator. For synchronizing the oscillation signals of the ring oscillator with an external oscillation signal a summator can be connected in the ring circuit.
