摘要

Leakage power is becoming the major constraints in deep sub-micron technology. A new technique named as adaptive logic cell (ALC) is proposed that is adapted the logic cell which is in their Worst Leakage State (WLS) to further reduce the overall leakage power dissipation of the circuit. Once Minimum Leakage Vector (MLV) is achieved by using heuristic or exact algorithm for a given logic circuit, this approach is applied. It finds a logic cell which is in WLS and switches it with another cell having least leakage power dissipation with the same input vector. This is extension of IVC technique in which the cell in WLS is replaced and also it controls the intermediate gate while IVC is responsible only for primary input of the circuit. This new approach of ALC in WLS is valid when the logic depth is large otherwise IVC technique is appropriate for reducing the leakage power. The proposed technique is process independent and also no extra power supply is required. Proposed technique is simulated for NAND, NOR, EX-OR, EX-NOR, Half adder and Full adder using HSPICE simulator and achieves 72.56%, reduction of leakage while IVC reduce only 47.07%.
