Described is an apparatus to lower power of a charge pump. The apparatus comprises: a first delay unit to receive a reference clock, the first delay unit to provide a delayed reference clock to a first sequential unit; a second delay unit to receive a feedback clock, the second delay unit to provide a delayed feedback clock to a second sequential unit; a first logic unit to receive the reference and feedback clocks, the logic unit to perform a logical OR operation on the received reference and feedback clocks, and to generate a trigger signal for a third sequential unit; and a second logic unit to receive outputs of first and second sequential units, and to generate an output coupled to the third sequential unit.
