No lecture tomorrow
Focus on the design of the LNA.
a) Single stage CS vs CG
b) Add cascode?
--- Pros vs cons
c) Biasing - via current mirror and/or resistive divider
d) Transformer for impedance transformation and input voltage boosting
--- PDK IND vs TRANSFORMER model (analogLib IND + MIND)
--- Inverting (CS/CG + negative current fb from source to gate) vs non-inverting (e.g., CG + positive current fb from drain to source)
e) Load - LC-tankCapacitor trimming?
--- Switched capacitor n/w
d) Setup the test-bench
--- DC, SP, PSS/HB (for P1dB: plot Pin vs Pout)
Explain your design choices, e.g., topology! Add pertinent design data, e.g., PDK component parameters, dc current, etc.
If you still haven't solved the filter yet, wrap that up fast.
Please ask questions in the lab!
