Theory

The design derivations behind the two sizing paths — read these to understand why the sizer computes what it does, not just the API surface. Analytical Sizing Flow covers the analytical Level-1 path: the square-law device equations, the CMRR → SR → GBW → gain → PM constraint order, the CP-SAT integer linearisation, and a worked numerical example. gm/Id Sizing Flow covers the gm/Id path: the five-phase procedural pipeline and the role vs functional-building-block tagging that fixes each device’s gm/Id. Which path runs for a given technology is decided in Sizer, Path selection.
