Hi
I have designed a low noise trransimpedance amplifier which has a GaAs
FET as an input transistor. I want to protect the input (gate) of these
fets from high voltage transients due to a RF source in proximity.
If i add Transient voltage suppressor/ zener - is that going to
deteorate my noise performance. Or can there be leekage issues in the
zener which can suck my signal current away from the FETs.
