Faux-moat bypassed

Gilbert-cell architecture is decades old (Gilbert 1968) but a verified sky130-port + characterization is not in any open catalog. Analog designers re-derive every time.

Value to customer

Drop-in analog tanh primitive for neural-network frontends, biosignal envelope detection, and any application needing sub-pJ-per-op nonlinearity. Characterized across temperature + corner + bias variations.
