Hello,
I am new in this field and i am designing gilbert cell mixer but i don't know how to do the input and output matching. Can anyone help me with this ????
Input Matching is simply like LNA matching so Conjugate Matching.LO port is hardly driven so it doesn't need matching.
Output Matching can be done by obtaining large signal output impedance ( Large Signal S-Parameters ) then apply a proper Conjugate Matching or Harmonic Matching that decreases harmonic contents at the output.( It's a little bit tricky but not too hard..)
