Abstract
This paper presents a high-speed pulse-based flip-flop with pseudo MUX-type scan compatible with the conventional master-slave flip-flop with MUX-type scan. The proposed flip-flop was implemented as the standard cell library using Samsung 130nm HS technology. The data-to-output delay and power-delay-product of the proposed flip-flop are reduced by up to 59% and 49%, respectively. By using this flop-flop, ARM11 softcore has achieved the maximum 1GHz operating speed.
