Analytical Sizer

The Level-1 square-law path, used for the card-less generic technology. Because each device’s IDS is fixed by KCL before geometry is chosen, the gm requirements linearise into an integer program over the discrete W/L grid and are solved for minimum gate area with OR-Tools CP-SAT. Level-1 Sizer is the driver that runs the solve and returns the sizing; Constraints builds the CP-SAT model — the linearised gm/VDS,sat constraints, the matched-pair symmetry, and the area objective. The derivation and a worked example are in Analytical Sizing Flow.
