Abstract(in English) | Domino logic was introduced at the forefront of the LSI market in the 2000s for high-speed circuits. In recent years, however, domino logic has been rarely introduced due to the unreliability factors such as large dynamic power and exponential increase of leakage current induced by the progress of fabrication technology. On the other hand, siliconon thin buried oxide (SOTB) has attracted attention as a new CMOS process technology. SOTB is a type of fully depleted silicon-on-insulator (FD-SOI), and its parasitic capacitance and leakage current are small due to its structure. In this report, we propose a high-radix tree adder that exploits these features of SOTB. To improve the performance of the proposed adder, we explore an appropriate transistor sizing based on the analysis of unreliability factors. The evaluation result shows that the delay of the proposed 23-bit, 64-bit high-radix tree adders are 3.2% and 1.8% smaller than that of the radix-2 tree adder, respectively. Moreover, by comparison with bulk CMOS, it showed high affinity of SOTB and domino logic. The 16-bit multiplier with the proposed adders shows 27.4% to 34.3% smaller delay than that of the standard-cell-based static CMOS designed by Synopsys Design Compiler. |
