Help me design a LNA in 0.18um technology and in 2.4GHz with ADS
we should have plots of NF vs freq & S11,S12,S21,S22 vs freq & IP3 & P1dB & Zin
thank you
There is LNA example in ADS design guide, you can follow it
how to set the resonance frequency ? for example we want to have the S parameters resonate in the 2.4 GHz,what should we do?what components in the cascode LNA influence the resonance frequency?
Hi, sasa0.
At first you should choose the structure of your LNA, for example - whether it is one or two stages, what type of amplifier is either stage will be (common-source, common-base,etc.).
The resonance frequency is determined by load LC tank. The parasitic capacitance from drain (or collector) of cascode transistor influences the resonance frequency.
tnx,
our structure is cascode,
we want to measure Zin and IP3 and P1-dB, how can we do it?
you could find some information about the LNA design here:

About the stabilization of your device see here:
