Abstract :
A new architecture of the analog mirror type DLL has been developed. A dynamic comparator and self-calibration feedback loop are employed. The operation error of less than 50ps is confirmed under the condition of 1.6V supply voltage and 1.4V internal voltage. The proposed circuit is suitable for low-voltage and high-speed applications
