Abstract
A phase detection circuit includes a phase frequency detector for comparing a first input signal and a second input signal and outputting a first phase comparison signal and a second phase comparison signal, and a sensing circuit for sensing a pulse width difference between the first phase comparison signal and the second phase comparison signal and outputting phase detection signals which have different logic values.
