| Abstract(in English) | We have proposed Self-Adjusted Forward Body Bias (SAFBB) technique, in that the current flowing through pn junction in transistors is limited to make forward body bias maximum. A 32bit adder was fabricated using 0.13um CMOS technology. It consumes 9uW at 50MHz which corresponds 1/30 energy of conventional ones. We have also proposed a gated body technique. The forward bias is applied at operation mode to speed up circuits, and cut off at standby mode to decrease leakage currents. A estimated power of LSIs for mPEG2 encoder could be decreased to 1/5 of conventional method. |
