Abstract :
A block activation/deactivation technique uses zigzag super cut-off CMOS to improve wake up time by 8/spl times/ in 0.6 /spl mu/m CMOS versus super cutoff CMOS. Our clock-gating substitute achieves a 200 ps wake-up time and 3 orders of magnitude leakage reduction for leakage dominant LSI´s.
