For HDTV system, the phase tracking loop is an additionaldecision feedback loop which further tracks out phase noise which has notbeen removed by the IF PLL. In this thesis, the general design andapproximation method of phase tracking loop are described.Furthermore, we discuss several architectures for high-speed operation.Finally, two phase tracking loop circuits of GA HDTV which have theproperties─computationally efficient, hierarchy, modularity, and localityare designed and realized. We use the COMPASS 0.6mm standard celllibrary and TSMC 0.6um SPDM technology to design by CADENCEtools. The highest frequency of chip is 70.97 MHz and operating on the70.97 Msymbol/sec.
