A technique that improves scan-shift speed by 60-100% through controlling power consumption during scan shift as shown by simulation results is presented. The technique exploits the quadratic relationship between power and voltage to significantly increase the scan-shift speed while staying within the same power budget constraints. The technique is also orthogonal to techniques that lower power consumption by controlling the activity ratio or gating the clock.
