Abstract
The present invention provides a voltage controlled oscillating circuit comprising a multi-staged phase inversion circuit composed of 4 or more even-number stages of phase inversion devices connected in series; and a switch circuit having a delay time characteristic similar to that of said phase inversion circuit, wherein the switch circuit satisfies oscillation conditions by converting an output phase of the even-numbered inverters connected in series into a phase that is the same as those of the outputs of odd-numbered inverters connected in series; thereby obtaining timing signals having a period equal to 1/N of the oscillation period.
