I am simulating multiband LNA using active inductor for wimax applications (2.6GHz,3.6GHz,5.5GHz)..in that i am using simple active inductor topology using feedback resitor(Rf), here tuning can be done for different values of Rf. If Rf increases results high quality factor also inductance increases but at the same time resonant frequency decreases. So that I am unable to get higher frequency 5.5GHz by tuning this active inductor. But some published papers i have seen that they obtained higher frequency also with same active indcutor... Can anyone tel me how it is possible to obtain higher frequency by tuning active inductor.
Thanks saam
