Clock-delayed (CD) domino is a dynamic logic family developed to provide both inverting and non-inverting logic on single-rail gates. It is self-timed and can be easily pipelined for superior speed performance which makes it an attractive option in high-speed logic implementation. This paper presents the design of two different high-speed pipeline configurations of a 32-bit carry look-ahead adder using CD domino gates utilizing efficient clocking methodology to reduce the overall critical path delay.
