anyone has information about IC phase detector?

[keen_observer]

I come across a question today regarding the phase detector inside an IC (integrated Chip)? Does anyone know how phase detctor being implement in IC? Or point me to the direction where i can find the information?

thanks in advance

There're lots of papers on this, just post some here. I didn't get chance to read them, so not sure whether it is helpful. Are you working on PLL stuff ?

Ebridge,

Thanks for the link. Looks like you are in the research field?

I was trying to find out how phase dector and frequency phase detector being implemented in IC from a top level. I have heard people mentioned using counter for lock detector in IC device. I am not very keen on this subject, and want to find out more information on this.

I think you are talking about PLL or frequency synthesizer. A phase detector basically is an XOR gate though most look a little more complicated. Mentor Graphics just had a free workshop not long ago in Ottawa.

My suggestion is you go to google.com and enter "pll,phase detector" as key words you will find hundred of examples in ICs.
