Anti-interference low-power double-edge triggered flip-flop based on C-elements

When the input signal has been interfered and glitches occur, power consumption of Double-Edge Triggered Flip-Flops (DETFFs) will significantly increase. To effectively reduce consumption, this paper presents an anti-interference low-power DETFF based on C-elements. The improved C-element is used in DETFF, which blocks signal, prevents redundant transitions inside reduces charge discharge frequencies transistor. also added pull-up pull-down paths, reducing its latency. Compared with other existing DETFFs, proposed only flips once clock edge, greatly caused by consumption. This uses HSPICE to simulate 10 DETFFs. findings show that compared types achieved large performance indexes total glitches, delays, delay product. A detailed analysis variance indicates features less sensitivity process, voltage, temperature, Negative Bias Temperature Instability (NBTI)-induced aging variations.
