Abstract
An improved successive approximation register (SAR) controller for all digital delay-locked loops (ADDLLs) is proposed to overcome the dead lock problem of the conventional SAR controller by embedding a restarting circuit module into the conventional SAR controller. The ADDLL that adopts the new SAR controller can track the operating frequency variation after the first lock-in, keep the advantages of the SAR searching algorithm and satisfy the requirements of DVFS systems.
