Abstract
A method includes generating N reference clocks with period T and phases uniformly distributed in 360 degrees; using each of the N reference clocks to trigger M intermediate signals with period M*T and phases uniformly distributed in 360 degrees; and performing a logic operation between at least two intermediate signals respectively corresponding to two different reference clocks to generate an output clock with period (M/N)*T to achieve non-integer frequency division.
