A Low-Power Level-Converting Double-Edge-Triggered Flip-Flop Design

摘要

This paper proposes a new double-edge-triggered implic­itly level-converting flip-flop, suitable for a low-power and low-voltage de­sign. The design employs a sense amplifier architecture to reduce the de­lay and power consumption. Experimentally, when implemented with a 130-nm, single-Vt and 0.84 V Vdd process, it achieves 64% power-delay product (PDP) improvement, and moreover, 78% PDP improvement when implemented with a mixed- Vt technology, as compared to that of the classic double-edge-triggered flip-flop design.
