Abstract
A phase detector includes a first flip-flop responsive to a reference clock signal, a first inverter responsive to an output of the first flip-flop, a second flip-flop responsive to a feedback clock signal, a second inverter responsive to an output of the second flip-flop, a third inverter responsive to an output of the first inverter, a fourth inverter responsive to an output of the second inverter, a first conjunction circuit responsive to the output of the first inverter and to an output of the fourth inverter, and a second conjunction circuit responsive to the output of the second inverter and to an output of the third inverter. The first conjunction circuit outputs a first alignment signal when the feedback clock signal is earlier than the reference clock signal, and the second conjunction circuit outputs a second alignment signal when the feedback clock signal is later than the reference clock signal.
