“…From Equation ( 4), CL dictates load capacitance of the latch at output node Q, VDD dictates the supply voltage of the latch and f dictates the frequency of operation for the latch. [10], [19]. It also dictates that as the technology scales down the parameters like power, latency & figure of merit also scale down respectively.…”

“…Pulse-Triggered Flip-Flop (PFF) is an option to help in penalty reducing or area diminishing due to its simple and compact structure [17,18]. However, high power consumption due to redundant switching activities and contention mechanism is usually an issue [14,19,20,21].…”

A power-efficient Single Event Upset (SEU) -tolerant pulsetriggered flip-flop design is presented. The dual-modular redundant design takes advantage of concise formation of pulse-triggered designs, and avoids the disadvantages of it, such as high power consumption. Clock-gating scheme is applied to reduce power consumption. The static configuration and the avoidance of contention mechanism led to the balance of power consumption, speed and SEU tolerance. The SEU tolerance is evaluated by means of SEU cross section, which is significantly lower than conventional D flip-flop. The proposed flip-flop is designed in 55nm CMOS technology to evaluate performances. The proposed design achieves the lowest power consumption, which is even lower than conventional D flip-flop. Although the speed is sacrificed, the lowest power-delay product is achieved among hardened designs. The proposed design provides solution to speedinsensitive and power-constrained applications.

A PVT variation-tolerant static single-phase clocked dual-edge triggered flip-flop for aggressive voltage scaling

A novel static single-phase clocked (SSPC) dual-edge triggered flip-flop (DET-FF) is proposed to allow energy-efficient operation with aggressive voltage scaling. By employing two static latches with a singlephase clock, contention and clock phase mismatch is avoided, which significantly improves tolerance to PVT variations. The post-layout simulation performed with 28 nm CMOS technology shows that the proposed SSPC DET-FF consumes less power and has significantly better powerperformance trade off (PDP) than prior-art DET-FFs. Our Monte Carlo analysis also showed that its supply voltage can be aggressively scaled down to 0.3 V even with PVT variations.
