Abstract
A phase-locked loop circuit includes a first circuit, a second circuit, and a voltage down converter. The first circuit generates a first signal based on a reference signal and a feedback signal, and operates based on a first supply voltage. The second circuit generates an oscillation signal based on a second signal, generates the feedback signal by dividing the oscillation signal, and operates based on a second supply voltage lower than the first supply voltage. The voltage down converter generates the second signal by decreasing an activation voltage level of the first signal. The voltage down converter includes at least one passive element electrically connected between the first circuit and the second circuit.
