The oscillation circuit (1) contains a mixer for the phase-shifted output signal (S2) and the input signal (S1) to provide a mixer signal (S3), from which a mean value is determined (3). The mixer is a flank triggered RS flip-flop (4), to which is fed the input signal at one input (R/S), and the phase-shifted signal at the other input (S/R). Either the input signal or the phase-shifted signal are additionally inverted in an inverter (5). The polarization of the direct part signal, resulting from the mean value determination, is adjusted in dependence of the inverter position and its link to the R or S flip-flop input.
