In this paper, a novel start-controlled phase/frequency detector (PFD) for multiphase-output delay-locked loops (MODLLs) is presented. In the proposed PFD, the start-controlled circuit is used to provide a precise multiphase-output without the locking problem. The PFD utilizes a new NAND-resetable dynamic DFF so that a shorter reset path is achieved. Thus,(More)
