RF Power Amp Driver TSMC N16FFC-RF (one stage)

 RF Power Amp Driver TSMC N16FFC-RF (one stage)

 (Apple C1 by TSMA N4P is more advanced, no longer apply, not even N3E)

PA LessonsPA Verified by computing the exact KCL residual at its converged solution, not because of blow up of MNA (share)




what has been changed (shifting not chasing, good)




MNA
Optimizer Apply MNA
what has been changed surfacereality






Optimizer Apply Harmonic (close the loop)
change v9 MNA vs V21 Harmonic





visualization (pt A&B by tuning v22 2.2*Vdd, 2*Vdd too tight)





block diagram artifact



RF PA driver with 10 dBm output, not PA itself (realistic spec, not just renaming)

TSMC N16FFC-RF revision (under construction)
