I was trying to design a low noise amplifier, so i

choose from the "transistor" menu BIPNPN gummel poon

BJT. I chose "infineon" transistor,placed the spice

parameters,biased it and matched it by using S

parameter and did linear analysis and somehow i

couldn't get the expected results. After rechecking

the circuit and using different models,different

biasing circuitry it didn't worked. Can you please

figure out the problem.
