The main objective of this thesis is to design a fully integrated charge pump PLL for application and integration on a high-frequency ghost cancellation chip. Since microprocessor operate at very high clock frequency, it becomes necessary to eliminate the delay between external and internal clocks (clock skew). This thesis will deal with the design of a charge pump phase-locked loop as a part of a high-performance ghost cancellation chip set. A charge-pump phase-locked loop (CPPLL) calibrates the delay per stage of the delay line. Using this technique, it is possible to obtain an accurate phase relationship between an off-chip reference clock and the internal clock signals. This CPPLL will be fully integrated onto a ghost cancellation chip in 2.0-um CMOS technology without the need for external components.
