Abstract :
The dead lock problem of conventional SAR DLL is discussed. Different improvement approaches to fix the dead lock problem of conventional SAR DLL are shown and compared. A new improved SAR controller whose relock-in steps are only 2 k is proposed in this paper. Its relock-in process is illustrated. Verification of this new SAR controller is done by Hspice simulation.
