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.
