Design And Implementation of Anti-Interference Low Power Double-Edge Trigger Flip-Flop Based On C-Element
Abstract: Double-Edge Triggered Flip-Flops (DETFFs) will use a lot more power when there are glitches and interference in the signal input. This work proposes an anti-interference low-power DETFF based on C-elements to efficiently lower the power consumption. This DETFF employs an enhanced C-element, which successfully filters input signal glitches, avoids redundant transitions within the DETFF, and lowers the transistor's charge and discharge frequencies. To lower its latency, the C-element has additionally …
