How to take S12 into consideration. Which parameters do I need to look for? Does it change my optimum load impedance?
I am working on power amplifer. If Matching starts from the last stage, doest my optimum load impedance change again after doing interstage matching at the output of M1 and M2(considering optimum load impedance at their drain terminals). Since It is power amplifier, I am ignoring NF. However, to do simultaneous matching I should use noise circles and gain circles right.
