Abstract :
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 um CMOS process. The validity and effectiveness are verified through the HSPICE simulation.
