Transistor level budgeting for power optimization [PDF]
SCS 2003. International Symposium on Signals, Circuits and Systems. Proceedings (Cat. No.03EX720), 2004 We present an optimal budget distribution method for low power circuit design using transistor sizing. The algorithm distributes the available budget inside the functional unit by efficient traversal of the Series Parallel Graph representation. The technique can be efficiently applied at different abstraction levels of the design as well as toward ...
