RF IC Design Optimization- LNA

LNA

cf: Apple C1 Transceiver Architecture 

3.5 GHz LNA N7 (closed-form), spec, N16,  share, slides,  Smith Chart in Optimizer, Smith Chart, Optimizer UI with synced sliders (closed-form),  

schematic 0.6 – 6 GHz (Sub-6),slides, slides+

GD/(A*)+MNA Optimizer on a Apple C1 LNA
Die artifact (MNA)

MNA Optimizer on Die (MNA all param.)

DE+MNA Optimizer on Die artifact (MNA all param.), what difference

Super (all merits above combined)

Optimized vs. Original (5 GHz), md, Reality check (slides), md

schematic

how to get this

running ngspice in Claude VM (findings, ill., also Cadence below, handout md)

initial parameters running MNA (findings, ill., handout md, detail md)

optimized parameters using MNA (share, handout md)

Use Cowork

analytical vs. MNA

auto-correction of model, auto-optimize parameters

until all specs pass
