In this paper we review the development & advantages of multi valued logic. The multi valued logic has been object of research over last few decades. Since 1971 there have been annual symposiums on multi valued logic. The use of non binary logic or discrete-analog signal processing is not out of the question if the multiple-valued hardware algorithms are developed for fast parallel operations. ...
We present designs of reversible Peres logic gate and FeynmanDouble logic gate based on all-optical switching by two-photon absorption induced free-carrier injection in silicon add-drop microring resonators. The logic gates have been theoretically analyzed using time-domain coupled-mode theory and all-optical switching has been optimized for low-power (25 mW) ultrafast (25 ps) operation with hi...
Logic-Based Switching Algorithms in Control João P. Hespanha Yale University 1998 This thesis deals with the use of logic-based switching in the control of imprecisely modeled nonlinear systems. Each control system considered consists of a continuous-time dynamical process to be controlled, a family of candidate controllers, and an event-driven switching logic. The need for switching arises whe...
The inverters are commonly used for medium power induction heating applications. In the process of induction cooking, a disc of metal is surrounded by a copper coil through which an alternating current is made to flow. The disc has a finite diameter and thickness. It is placed at a given distance from the coil and concentric to it. Secondary current is induced in the disc and this induced curre...
As the density and operating speed of complementary metal oxide semiconductor (CMOS) circuits increases, dynamic power dissipation has become a concern in the design of VLSI circuits. This paper presents a Two-Phase Adiabatic Static Clocked Logic (2PASCL) which shows the lowest power dissipation among different adiabatic logic families based on energy recovery principle. In adiabatic switching ...
The overall objective of these lectures is to overview a variety of methods for synthesizing and analyzing logic-based switching control systems. By a logic-based switching controller is meant a controller whose subsystems include not only familiar dynamical components {integrators, summers, gains, etc.} but logic-driven elements as well. The overall models of systems composed of such logics to...
We address the problem of controlling a linear system with unknown parameters ranging over a continuum by means of switching among a 4nite family of candidate controllers. We present a new hysteresis-based switching logic, designed speci4cally for this purpose, and derive a bound on the number of switches produced by this logic on an arbitrary time interval. The resulting switching control algo...
This paper presents an innovative architecture for a reconfigurable device that allows single cycle context switching and single cycle random access to the unified on-chip configuration/data memory. These two features are necessary for efficient self-reconfiguration and are useful in general as well—no other device offers both features. The enhanced context switching feature permits arbitrary r...
By adopting certain techniques in the design of your CMOS-based logic system, you can effect dramatic reductions in the transitional power these zero-quiescent-current devices consume when switching. This article describes ways to reduce the power consumption in logic designs using high-speed CMOS ICs. The MM74HC logic family has near-zero power dissipation when in the quiescent mode. Its only ...
