We present a mixed-mode delay-locked loop (DLL) architecture intended for multiple-phase clock generation. In contrast to analog DLLs, the proposed architecture allows for clock-gating; moreover, circuit simulations indicate that its performance (in terms of maximum frequency, frequency range, and low-speed power dissipation) is superior to that of a previously-reported, purely digital DLL.
