Crosstalk from digital to analog circuits can be causative of operation fails in analog-digital mixed LSIs. This paper describes modeling techniques and simulation strategies of the substrate coupling noise. A macroscopic substrate noise model that expresses the noise as a function of logic state transition frequencies among digital blocks is proposed. A simulation system based on the model is ...

Phase-locked loops (PLLs) are used in wireless receivers to implement a variety of functions, such as frequency synthesis, clock recovery, demodulation, and mixed-signal integrated circuits. Substrate coupling noise is a key problem in today’s large mixed-signal systems. Switching-noise generated by digital circuits can be coupled to sensitive analog circuits through the substrate, can degrade ...

Two different natural dyes containing anthocyanin extracted from black carrot and bramble from Iran. Spectrophotometric evaluations of the natural dyes in solution and on a TiO2 substrate were carried out in order to assess changes in the status of the natural dyes. The results show that the natural dyes indicate buthochromic shift on the TiO2 substrates. The chemical adsorption of natural dyes...

Oligosaccharyltransferase (OTase) glycosylates selected asparagine residues in secreted and membrane proteins in eukaryotes, and asparagine (N)-glycosylation affects the folding, stability and function of diverse glycoproteins. The range of acceptor protein substrates that are efficiently glycosylated depends on the action of several accessory subunits of OTase, including in yeast the homologou...

The transient behavior of a continuous culture of Klebsiella pneumoniae with mixed feed of glucose and xylose arising from step-up and step-down in dilution rates and from a feed-switching experiment is presented. he organism gradually switches from simultaneous utilization of the substrates at low growth rates to preferred utilization of the faster substrate (i.e, supporting a higher growth ra...

The lack of complete understanding of the substrate effects on carbon nanotubes (CNTs) growth poses a lot oftechnical challenges. Here, we report the direct growth of nanostructures such as the CNTs on stainless steel 304and brass substrates using thermal chemical vapor deposition (TCVD) process with C2H2 gas as carbon sourceand hydrogen as supporting gas mixed in Ar gas flow. We used an especi...

A factorial experiment was conducted to evaluate the impact of super absorbents and organic wastes of rice, olive marc, vermicompost and farmyard manure on the soil water holding capacity and the growth of plant based on randomized complete block design with 13 treatments at two irrigation intervals 5 and 10 days. The olive saplings with same heights and better appearances were planted...
