DWM (Directional weighted median) filter is very popular in filtering digital image and remove mixed noise. Fuzzy logic implemented with median filters to improve its performance. In the previous work, fuzzy system switching gives better performance than directional as well filter. Experimenting same didn’t yield results therefore parameters has been changes per strong points of a constant incl...

An eecient technique to reduce the switching activity in a technology mapped CMOS combi-national circuit based on local logic transformations is presented. The transformations consist of adding redundant connections or gates so as to reduce the switching activity. Simple and eecient procedures, based on logic implication, for identifying the sources and targets of the redundant connections are ...

AbstraceIn this paper, the efficiency of a fully adiabatic logic circuit is compared with its combinational and pipelined static CMOS counterparts. The performance of each circuit is studied in terms of the maximum frequency of operation, the minimum voltage of operation, the circuit energy consumption, and the switching noise generated by the circuit. An 8-bit carry look-ahead adder is designe...

With the technology down scaling the area of each device in a chip reduces. Lesser area increases the power consumption. In current technologies leakage current is the major part in power consumption. Power gating is a technique which has been used to reduce leakage power by shutting off the power when no activity done by the logic. These helps to reduce the power consumption, delay and switchi...

This letter presents the experimental demonstration of a Coulomb blockade ~CB! logic device. Our logic architecture consists of an array of current pathways, controlled by CB switching nodes. In this architecture, high gain is not required to transmit information, making it well suited to the CB device. Each CB node is switched between a blockaded state and a completely pinched-off state, minim...

This paper presents an algebra of idempotent substitutions whose operations have many properties. We provide an algorithm to compute these operations and we show how they are related to the standard composition. The theory of Logic Programming can be rewritten in terms of these new operations. The advantages are that both the operational and the declarative semantics of Horn Clause Logic can be...

This paper presents the optimization of shunt active power filter parameters based on fuzzy logic control. The current active filter control is based on constant, fuzzy hysteresis band techniques, which are employed to derive the switching signals and also to choose the optimal value of the decoupling inductance. The DC voltage controller optimizes the energy storage of the DC capacitor, where ...

This paper deals with PID compensator control of Synchronous Rectifier (SR) Buck Converter to improve its conversion efficiency under different load conditions with the help of a Zero Voltage Switching(ZVS)Logic Circuit. Since the freewheeling diode is replaced by a high frequency switch MOSFET in this buck configuration, the SR control technique itself will be sufficient under heavy load condi...

Abstract A new high-speed and low-power threshold detector is proposed to realize high-performance arithmetic VLSI systems. In a conventional threshold detector with a single supply voltage, the input signal swing of a differential-pair circuit (DPC) is too large, which causes large power dissipation together with a long switching delay. The use of two kinds of supply voltages makes the input s...
