A router chip, that incorporates on-chip forward body biasing capability with 2% area overhead, achieves 1 GHz operation at 1.1 V supply in a 150 nm logic technology, compared to 1.25 V required for the original design having no body bias. Switching power is 23% less and chip leakage is reduced by 3.5/spl times/ in standby mode by withdrawing forward bias.
