hi all
I'm trying to design a cascode amplifier in resonance, here is the
schematic:
http://www.thebags.it/listing/uni/cascode_sc.png
my project target are:
gain 20dB
resonance frequency 850Mhz
BW 100Mhz
but I've a problem ..I am not able to set the resonance frequency at
850Mhz; every combination of C and L I try I always get these
resonance frequency: 629Mhz, 792Mhz, 997Mhz, 1256Mhz.
here is a little parametric analysis:

how is it possible? I tried to edit all the circuit parameter in order
to understand the reason but I always get these values
any help is appreciated!
thanks
Matteo
