1. (a) Run NGSpice for the LNA using given parameters. If the results do not match, explain why.

(b) Run an MNA simulation (Modified Nodal Analysis, as used in Cadence Spectre engine)

2. Perform DRC (Design Rule Check) for the  3.5 GHz LNA. If it is not entirely design rule compliant, redesign to make the layout more DRC driven.

3. (a) Run the Simplified LNA optimizer on Die, 3.5 GHz LNA TSMC N7. Use MNA (Modified Nodal Analysis, as used in Cadence Spectre engine)  to optimize again.

(b) To achieve the 15-20 dB gain target and improve the LNA performance to match the schematic specs, use Differential Evolution Optimization to optimize the LNA performance.
