Cdv/dt induced turn-on of the synchronous MOSFET deteriorates performance in synchronous buck regulators. We will discuss this problem and provide several solutions that can reduce the effects. SYNCHRONOUS BUCK REGULATOR Synchronous buck topology is becoming popular in powering ultra-fast CPU cores. A standard buck circuit is shown in Figure 1(a) and a synchronous buck is shown in Figure 1(b). ...

We propose an anti-parity-time (anti-$\mathcal{PT}$) symmetric non-Hermitian Su-Schrieffer-Heeger (SSH) model, where the large non-Hermiticity constructively creates nontrivial topology and greatly expands topological phase. In anti-$\mathcal{PT}$-symmetric SSH gain loss are alternatively arranged in pairs under inversion symmetry. The appearance of degenerate point at center Brillouin zone det...

We give some easy to use criteria for deciding whether a MM obius plane, Laguerre plane or Minkowski plane, given in some normal form, is 2-dimensional. As an application of our results we prove that a Laguerre plane or Minkowski plane with a given topology on the point set is a (topological) 2-dimensional plane if and only if each derived aane plane at points of at least one parallel class is ...

The Besicovitch pseudodistance measures the relative size of the set of points where two functions take different values; the quotient space modulo the induced equivalence relation is endowed with a natural metric. We study the behavior of cellular automata in the new topology and show that, under suitable additional hypotheses, they retain certain properties possessed in the usual product topo...

In the current paper, consider the fuzzy normed linear space $(X,N)$ which is defined by Bag and Samanta. First, we construct a new fuzzy topology on this space and show that these spaces are Hausdorff locally convex fuzzy topological vector space. Some necessary and sufficient conditions are established to illustrate that the presented fuzzy topology is equivalent to two previously studied fuz...

The purpose of the present work is to introduce the concept of bifuzzy core of a fuzzy automaton, which induces a bifuzzy topology on the state-set of this fuzzy automaton. This is shown that this bifuzzy topology can be used to characterize the concepts such as bifuzzy family of submachines, bifuzzy separable family and bifuzzy retrievable family of a fuzzy automaton.
