Abstract :
A new sense-amplifier based flip-flop (SAFF) is proposed to improve the transition delay and to reduce the power consumption in comparison to those of existing SAFF designs. The speed improvement of the proposed SAFF is achieved by reducing the delay of the holding stage as well as the delay of the sampling stage. Power consumption is reduced by introducing a novel conditional precharge technique. The performance of the proposed flip-flop is simulated in SPICE with 0.18 μm CMOS technology. A performance comparison with existing SAFF designs is also included in this paper. The comparison results show considerable power-delay-product (PDP) improvement of the proposed SAFF design at low input signal switching activity.
