PURPOSE: A phase locked loop and a method for driving the same are provided to remove the phase offset between a reference clock and a feedback clock by implementing a phase locked loop and a delay locked loop. CONSTITUTION: In a phase locked loop and a method for driving the same, a phase locked loop(100) compares the phase of a feedback clock with the phase of a reference clock. The phase locked loop generates an internal clock. A delay locked loop(200) compares the internal clock with the reference clock. The delay locked loop generates a feedback clock. The feedback clock is delayed according to a control voltage. An initial voltage driving unit(300) applies an initial voltage to a control voltage.
