Title: miller capacitor in pll loopfilter
Post by jjv on Jul 27^th, 2012, 4:38am

Hi,
Is there possibility of using miller multiplied capacitor in PLL loopfilter.
Have not seen any paper utilising this method except one by Rincon Mora. Just wondering if there is any disadvantage of using miller multiplied capacitor.

Thanks,
JJV.
