hi,,
any one has idea what is peaking inductor?
i find that it's used in filter design to increase the signal BW?
waiting :?:
 

Re: peaking inductor?

Hi,
As you know that inductor introduces a zero in the frequency response.
The peaking inductor is used to introduce a zero so that the frequency roll off is reduced and thus the bandwidth improves.
The peaking inductor can be used either in series or shunt.

Thanks

HI,,,
Thank you very much "Shaikh", could u explain more or u send me any materials which explain more with examples, sorry for that and waiting for ur reply
thankx

hi , try to check the section of braodband techniques in Razavi's optical communications book , section 5.2 broadband techniques including the inductive peaking

Re: peaking inductor?

Check Tom Lee's RF book, there's one chapter talking
about high speed amplifier and shunt peaking via inductor
is covered in great detail. By picking different values, you
can achieve maximum BW, maximum flatness, and best
phase response.

Hi,
thanks to all , check also the section of braodband techniques in Razavi's optical communications book , section 4.6.4 inductive peaking

In very high frequency oscillator's peaking inductor is used.
