发明名称 Oscillation circuit, testing apparatus and electronic device
摘要 Provided is an oscillation circuit for generating an oscillation signal synchronized with a supplied reference clock, including: a voltage control oscillation section that, when triggered by each edge of the reference clock, stops oscillation of the oscillation signal having a frequency in accordance with a supplied control voltage to start new oscillation; a phase comparing section that compares a phase of a comparison signal that is in accordance with the oscillation signal outputted from the voltage control oscillation section and a phase of a signal that is in accordance with the reference clock; and a voltage control section that supplies the control voltage in accordance with a comparison result of the phase comparing section, to the voltage control oscillation section.
