METHOD AND CIRCUIT FOR SUPPLYING MULTI-PHASE CLOCK WITHOUT BLOCKING RELATED TO DYNAMIC LOGIC

摘要

PROBLEM TO BE SOLVED: To provide a dynamic logic clock supply system with which full cycle time can be effectively utilized for logical operation without any factor to increase delay in a non-overlapped two-phase clock supply system. SOLUTION: The multi-phase clock supply system without blocking to be used for a dynamic logic applies a clock phase having an evaluation stage overlapped to a circuit provided with several cascade-connected dynamic logic gates 301-306. By appropriately allocating clock signals to the overlapped evaluation stage and the dynamic logic gates 301-306, output signals generated by the dynamic logic gates 301-306 receiving specified clock phases are utilized as input signals to the dynamic logic gates 301-306 receiving the next clock phases. Since the clock phases are overlapped, this circuit can be constituted without using any latch.
