In this paper, we present a bio-inspired model for detecting edges based on mathematic analysis of artificial retina response. And then mathematical analysis as well as computational design methods on the proposed retina model are dealt with. The characteristics of our model is that it just concerns four types of cells rather than traditional ones with five types of cells. Experimental results show...
In this paper an all digital phase-locked loop (ADPLL) that is based on double edge triggered D-flip-flops (DETDFF) was proposed. By using DETDFF, the functions of bi-directional zero crossing sample and phase detection, which are key issues in the designing process of ADPLL with several new important characteristics, were implemented. In addition, the run speed of each part in the loop was enhanced...
