Abstract
A dynamic incrementer, implemented in the Self Resetting Complementary Metal Oxide Semiconductor (SRCMOS) circuit family, which internally performs single rail calculations and which generates the dual rail result using a strobing technique. The carry-lookahead function is implemented with an OR tree using the complement input signals, resulting in a very fast and economical incrementer.
