Abstract
The present invention discloses a spike free circuit, which comprises a first flip-flop stage, a time shift means, a group of logic gates and a second flip-flop stage. The first flip-flop stage is triggered by a first edge of a clock signal. The time shift means is electrically connected to the first flip-flop stage and triggered by a second edge opposite to the first edge of the clock signal. The time shift means shifts input signals, which change logic level within the first to the second edges of the clock signal one half cycle for preventing spike occurring. The group of logic gates is connected to the time shift means. The second flip-flop stage is electrically connected to the group of logic gates and triggered by the first edge of the clock signal.
