RF PA IC Design

PA Sub 6 GHz

Load-Pull Contours

Build Sub 6 GHz Power Amplifier Optimizer with Die Synced

Placement

original, fixed (hardcoded), SA 1, QP, QP+SA (MNA, Small WireLen, non 0 viol.), 

• QP+SA with adaptive cooling schedule (2.55 WireLen, usual. 0 viol.) 
• add congestion penalty in energy (track overflow significantly reduced,  Bench, Overflow Comp, viz, detail viz)

PA Parameter Optimization

original (analytical), Hessian, MNA (post QP+SA)

PA Lessons, Apple C1 PA Verified by by computing the exact KCL residual at its converged solution, not because of blow up of MNA (share)
