Summary :

A novel body potential-controlling technique for floating SOI CMOS circuits is proposed and verified in this study. High-speed operation is realized with a small chip size by using body-floating SOI transistors. The use of this technique allows the threshold voltage of the body-floating transistors to be varied transitionally. Therefore, the standby current of SOI CMOS logic is reduced to less than 1/50th of that required by the non-controlled operation of the body potential, and the logic operates at a high speed during the active period. There is no speed penalty for the recovery operation from the standby mode. This technique supports sub-1 V operation, which will be required by future battery-operated devices with wide-range covering.
