How to optimize the settling time after the lock in PLL?

[dinesh agarwal]

some guide me how to optamise the settling time after the lock.
the PLL is PDF , charge pump ,passive filter order iii, nd uses LC osc.

PLL settling time

the settling time , depend on my paramters , the step or the jump in frequency , the gain of the PLL and the BW of the PLL

so u need to optimize it within all these paramters , so ur PLL give u the disred performance

Re: PLL settling time

dear dinesh agarwal :

You need to have a transfer function of your pll.
Than you can use matlabe and control system principle
to optimize the settling time that you want.
