hi,
what is the disadvantage of current reuse topology of LNA.
Thanks
 

Possibly a higher supply voltage needed. And one more inductor, depending on the topology used.
 

Other issues could include things like distortion,
or other nonlinearity, if the signal also modifies
its amplifier biasing in-the-moment.
