Methods and circuits for optimizing performance and power consumption in a circuit design and circuit employing one or more lower threshold voltage (Lvt) cells or devices are described. A base supply voltage amplitude is determined for providing operating power for the circuit. The base supply voltage amplitude is a low or lowest voltage level that still satisfies a performance specification for the circuit. Providing a low or lowest base supply voltage level reduces or minimizes the standby (i.e., non-switching) power consumption in the Lvt device(s) since current leakage is reduced as the supply voltage level is reduced. Reducing the supply voltage level used to power the Lvt device(s) also reduces active power consumption for the circuit as well. Thus, total power consumption is optimized or reduced while still receiving the benefit of using Lvt devices to optimize or increase performance of a circuit layout and circuit.
