摘要： A voltage controlled oscillator comprises a phase locked loop section (1) and a voltage controlled oscillator section (2). The phase locked loop section (1) is coupled with an input signal (Fref) at a reference frequency and a reference potential (Vref), and performs a signal feedback control so as to obtain a constant delay time of a first variable delay circuit (3) contained in the phase locked loop section. The voltage controlled oscillator section (2) controls a delay time of a second variable delay circuit (10) in a ring oscillator by a control input voltage (Vcont) and an output voltage (Voff) of a low-pass filter (7) contained in the phase locked loop section, and produces a signal oscillating at a frequency as determined by the delay time. In the voltage controlled oscillator thus arranged, the output frequency is determined by controlling a delay time of the second variable delay circuit in the voltage controlled oscillator section. Since the delay time is accurately controlled by the phase locked loop section, the obtained output frequency is stable against the variance of the process parameters. Since the delay time is varied by the reference frequency of the input signal, the output frequency may be set at a desired frequency, and hence a frequency band of the oscillation frequencies may also be set appropriately.
