    • In a disc reproducing apparatus using a VCO (voltage controlled oscillator) circuit, the VCO circuit includes a first delay cell array having gates supplied with a first control voltage DCV, a ring oscillator including a second delay cell array having gates supplied with a second control voltage Vin, and a switch for selecting the number of delay cells from the second delay cell array. The oscillation frequency of the ring oscillator is determined by a time delay of the second delay cell array. When the second control voltage Vin having the same value as the first control voltage DCV is inputted to the gates of the delay cells of the second delay cell array, the ring oscillator oscillates with a frequency determined by the ratio of the number of the delay cells of the first delay cell array to number of the delay cells of the second delay cell array. By operating the selection switch to change the number of delay cells constituting the second delay cell array, the voltage controlled oscillator (VCO) circuit can generates a signal of an oscillation frequency of a frequency division ratio other than 1/2.sup.n, by using at least one reference clock.
