Based on the partially-depleted, thin-film SOI/CMOS technology, the influence of reduced junction capacitance on the performance of the elementary gates and large scale gate array chip is reviewed. To further reduce the power consumption, SOI-specific device configurations, in which the body-bias is individually controlled, are effective in lowering the supply voltage and hence the power consumption while keeping the circuit speed. Two attempts are introduced: (1) DTMOS (Dynamic-Threshold MOS)/SOI to achieve ultra low-voltage and yet high-speed operation, and (2) ABB (Active-Body-Bias) MOS to enhance the current drive under the low supply voltage.
