This paper describes a low-power carry look-ahead adder with triple-threshold CMOS technique. 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%.
