Questions on the charge pump for PLLs.

g94426 · May 20, 2005

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!

Thank you!
And I thought the output of my PLL is in GHz range so that the question should be posted here. I'll put it at the right place. Thanks again.

But the charge pump is operating at the reference frequency, which is in order of few MHz.

U r welcomed
