Globalized bulk biasing based substrate noise reducing method for size reduction in digital circuit
DescriptionTechnology scaling results in smaller die size with increased amount of bulk-biasing penalty. In this paper, we propose a physical synthesis methodology for digital circuit that minimizes the overhead. Considering bulk-biasing constraint of mutual distance and density, we first place global bulk-biasing active before standard cell placement. Then, to guarantee the biasing constraints, we transform the placement using slide-window algorithm. For 3D V-NAND digital design [1], measurement result showed 7.2% of area reduction compared to the conventional methodology.
