Hello,
Please note that you have to describe your question, for example some prople may not be femilier with m, i guess it will be R*R*C/L.

So coming to your Question it depends on the application, for example if you want to design pulse amplifiers, you have to chose inductor in such a way that m=3.1, for max BandWidth it should be 1.41. You find can more details in TH lee book.

Thanks,
Raj.

hello,
without peaking, you can use 1.41 as i explained in the previous post. but you can get more BW but you have to compremise on peaking in magnitude responce. But accodring to bode integral max BW you can 2 times (accoring to theory) than without inductor case.

I forgot where i read this concept, otherwise i would have given the reply.

Thanks,
Raj.

There are several new inductive-peaking techniques for bandwidth enhancement of low-voltage CMOS current amplifiers. The techniques improve the bandwidth by utilizing the resonance characteristics of LC network by employing bond wire capacitance or on-chip spiral inductors. Both series-peaking and shunt-peaking techniques are considered.
