Abstract
A method is disclosed for utilizing mixed low threshold voltage (low-Vt) and high threshold voltage (high-Vt) devices in a cell-based design such that a tradeoff of both the circuit speed and power performance may be achieved. Using cells having non-uniform threshold devices for designing circuit, the speed or/and power optimization is comparable to fully custom designs.
