摘要： An oscillator circuit complementarily increases or reduces, in response to a transition of a signal level of a reference clock, a signal level of a first oscillation signal and a signal level of a second oscillation signal. An oscillation control circuit compares the first and second oscillation signals to a comparison voltage, and transitions the signal level of the reference clock in accordance with a result of the comparison. A reference control circuit increases or reduces the comparison voltage so that a difference between a signal level of an intermediate signal which is proportional to respective swings of the first and second oscillation signals and a reference voltage is reduced. A reference voltage control circuit increases or reduces the reference voltage according to a frequency difference between a basis clock and the reference clock.
