摘要：A phase locked loop may include: a phase detector receiving a reference signalfrom the outside and detecting a phase difference between the reference signal and adivided signal, a voltage controlled oscillator generating an oscillation signal

corresponding to a result detected by the phase detector, a first divider providing thedivided signal generated by dividing the oscillation signal depending on a first divisionratio to the phase detector, and a delta sigma modulator receiving the reference signaland the oscillation signal to perform delta sigma modulation. The delta sigma modulatormay be operated depending on a clock corresponding to a frequency of the oscillationsignal in a first section and operated depending on a clock corresponding to a frequencyof the reference signal in a second section.
