Low-Power Carry Look-Ahead Adder With Multi-Threshold Voltage CMOS Technology

摘要：

Multi-threshold CMOS (MTCMOS) technology provides the transistors that have low-,normal-,and high-threshold voltage. This paper describes a low-power carry look-ahead adder with MTCMOS technology. While the low-threshold voltage transistors are used to reduce the propagation delay time in the critical path,the high-threshold voltage transistors are used to reduce the power consumption in the shortest path. Comparing with the conventional CMOS circuit,the circuit is achieved to reduce the power consumption by 14.71% and the power-delay-product by 16.11%. This circuit is designed with Samsung 0.35 urn CMOS process. The validity and effectiveness are verified through the HSPICE simulation.
