ABSTRACT:
In a method and apparatus for generating a power supply voltage, an integrated circuit including an adaptive power supply voltage circuit is provided where a target signal is generated representing an ideal or approximated ideal performance characteristic of a functional block operating with the power supply voltage. A generated functional block test signal is generated representing the performance characteristic of the functional block under these conditions. The adaptive power supply voltage circuit compares the target signal with the generated functional block test signal and adjusts the power supply voltage continuously until the target signal and generated functional block test signal are substantially equal. When the target signal and generated functional block test signal are substantially equal, the power supply voltage is locked for subsequent use. By optimizing the power supply voltage, minimal power dissipation is provided.
