ABSTRACT
Conventional edge triggered flip-flops sample a data signal synchronizing with single clock edge. If a noise signal occurs around the clock edge, flip-flops result in malfunction. Then, we have proposed dual edge triggered flip-flops to solve this problem. The flip-flop has highly ability to prevent sampling a noise signal on a data line because it samples the data signal synchronizing with both of the rising edge and the falling edge. In this paper, we design a new circuit of the dual edge triggered flip-flops to improve circuit size, power consumption, and operation speed. In addition, we apply the dual edge triggered flip-flops to signal delay detection.
