Abstract
An electronic device includes a first circuit which refers to an external clock and thus produces a first internal clock, and a second circuit which refers to the first internal clock and thus produces a second internal clock. The first circuit has a first phase error between the external clock and the first internal clock, and the second circuit has a second phase error between the first internal clock and the second internal clock. The first phase error has a sign reverse to that of the second phase error.
