Abstract
A phase locked loop circuit includes a first current source that outputs a current from a first output node. The phase locked loop circuit includes a driving current circuit that includes a first voltage node set at a voltage corresponding to a supplied current and outputs a driving current from a driving current node according to the current supplied to the first voltage node. The phase locked loop circuit includes a current-voltage converter circuit that includes a second voltage node set at a supplied current. The phase locked loop circuit includes a first current switch circuit that electrically connects the first output node and the first voltage node or electrically connects the first output node and the second voltage node. The phase locked loop circuit includes an oscillator that receives the driving current and changes an oscillatory frequency according to a magnitude of the driving current.
