Abstract :
The conventional SAR controller for DLL applications is shown in this paper to have the problem of dead lock. With this problem, the DLLs adopting the SAR controller are useless because they will go unlocked forever in face of supply voltage and temperature variations. An improved SAR controller is proposed to overcome this problem and then to rescue the DLLs
