Abstract

To solve the locking problem of a conventional delay-locked loop, the present invention provides a delay-locked loop featuring multiphase output, wherein a phase/frequency detector (PFD) with a start control function can eliminate the locking problem and also provide a set of correct multiphase output signals. In addition, the phase/frequency detector of the present invention consists of two new type NAND resetable dynamic D flip flops such that the reset path required by the detector can be effectively reduced, and low power consumption and high speed operation can be achieved. The voltage controlled delay device of the present invention can operate in a low working voltage and the dead-band problem of the voltage controlled delay line can be prevented from happening.
