Significant challenges imposed on the design and optimization of clock-dependent systems have re-sparked interest in alternative circuit design approaches. Null Convention Logic, a quasi-delay-insensitive asynchronous design paradigm has gained significant support recently due to its intuitive circuit design and optimization approaches as well as its readiness for design automation. Just as for synchronous...
Compared to its synchronous counterpart, asynchronous design potentially provides many advantages in terms of power consumption, execution speed, and circuit reliability. This paper presents and discusses a complete new asynchronous circuit design flow of an 8-point Fast Fourier Transform circuit, a common building block in digital signal processing applications, starting from the radix-2 8-point...
Short reverse recovery time of a p-n junction is critical for high speed semiconductor device operation. This time period is a result of recombination processes when a p-n junction is switched from forward bias to reverse bias. Minority carrier lifetime is the major parameter determining the duration of reverse recovery. Three main poly-types of Silicon Carbide (SiC) including 4H-SiC, 6H-SiC and 3C-SiC...
In this study, a novel layer-by-layer polyaniline/graphene (PANi/Gr) structure for electrochemical detection of atrazine was developed. Gr film was synthesized by thermal chemical vapor deposition (CVD) method and transferred onto the PANi-predeposited microelectrode. The properties of PANi/Gr film were thoroughly investigated by high-resolution transmission electron microscopy and Raman techniques...
