Abstract
A delay-locked loop (DLL) and corresponding method improve frequency of a chip. The DLL comprises a first programmable delay element configured to output a first clock, a second programmable delay element configured to output a second clock a phase detector. The phase detector includes a first clock input and a second clock input. The first and second programmable delay elements are further configured, in combination, to introduce a controllable skew between the first and second clocks. The DLL is configured to input the first and second clocks to the first and second clock inputs of the phase detector, respectively. The controllable skew is configured to improve the frequency of the chip.
