| Abstract: | A method of phase-detected loop is presented by analyzing the principle of Costas loop. The loop parameters can be adjusted ,which guarantees the loop working well. The parameters and design of each part of the loop are described in detail. The internal signals of FPGA （field programmable gate array） observed by ChipScope Pro and the simulation results show that high performance can be achieved using this kind of Costas loop. |
