I'm designing a differential CMOS LNA and its output needs to match to
100 Ohms DIFFERENTIAL. What does this differential mean? Does it mean
that I take each transistor output impedance and match it to 50 Ohms or
it involves something entirely different??
Assuming this is how I match, only for simulation purposes if I use an
ideal balun to convert diff. to single-ended would I terminate the
single ended side at 50 Ohms or 100 Ohms? What I'm asking is the port2
terminal would have 50 or 100 Ohm reference impedance?? Someone please
answer...thanx
