Abstract :
A 0.35 μm bulk CMOS VLSI processor chip is compared with two SOI implementations (0.25 μm and 0.50 μm). The 0.35 μm bulk chip dissipates 16 mW at 69 MHz and the 0.25 μm SOI chip dissipates 28 mW at 73 MHz. The higher dissipation of the SOI chips was due to the layout conversion process. The area increased by 2.3× and 6.3× for the clock networks of the SOI chips but the measured clocked capacitance only increased by 1.6× and 1.7×. This result indicates that removal of the grounded substrate greatly reduced the effective clocked capacitance per unit area for the SOI chips
