Abstract :
Low-power, high-speed CMOS circuit design by means of supply-voltage (VDD) and threshold-voltage (VTH) control is presented. Recent research achievements of MTCMOS and VTCMOS are described. Clustered voltage scaling to lower VDD for non-critical circuits is discussed. Design examples such as an MPEG-4 codec LSI are presented. Circuit designers can control VDD and VTH as objectives of design optimization. As a result, active power can be reduced to below half, while static power and chip throughput are maintained
