attractive as a technique for both static and dynamic power reduction. Since
a reduction in supply voltage degrades performance, similarly to multi-V
th
designs, low V

must be used on noncritical gates to preserve performance.
With respect to the multi-V
th
case, the use of multiple V

s has an additional
constraint due to the fact that when two different voltage domains have to be
interfaced,
