Is there anyone could tell me how to design the charge pump circuits in front of the loop filter of a PLL? Is there any ICs available for this purpose? and how to select an appropriate IC?
I just start to learn to design a PLL and appreciate any help. Thanks first!
I designed a cmos PLL frequency synthesizer. For a charge pump is important to consider the dead zone and load redistribution, if you want to have a better phase noise response.
