Abstract
Provided is a phase locked loop circuit that includes: a phase comparison section configured to compare a phase of a first clock signal and a phase of a second clock signal; a loop filter configured to generate a control voltage based on a comparison result by the phase comparison section; and a clock signal generation section configured to generate a clock signal having a frequency corresponding to the control voltage, and output the clock signal as the second clock signal. The loop filter includes a first resistor inserted between a first node on a signal path and a second node, a first capacitor inserted between the second node and a first DC power supply, a first switch inserted between the second node and a third node on the signal path, and a second capacitor inserted between the third node and a second DC power supply.
