An effective approach to timing and power optimization for single clocking and multiple clocking dynamic CMOS designs is presented in this thesis. For the single-clocking scheme dynamic CMOS sub-blocks can be replaced by static CMOS and mixed-dynamic-static CMOS for power minimization. For the multiple-clocking scheme the delay of data ready for use plays more important role than its clock pulse in timing optimization. Power minimization can be achieved by implementing dynamic CMOS sub-blocks with static or mixed-dynamic-static CMOS. In comparison with the benchmark 16-bit carry select adder in dynamic CMOS, the critical path delay is reduced by 41.1% using the single-clock optimization approach; the power and delay are reduced by 43% and 41.1% respectively using the multiple-clock optimization approach. In comparison with the benchmark 64-bit comparator in dynamic CMOS, the critical path delay is reduced by 49% using the single-clock optimization approach; the power and delay are reduced by 43.1% and 49% respectively using the multiple-clock optimization approach
