This paper addresses certain inherent limitations of local priority hysteresis switching logic. Our main result establishes that under persistent excitation assumption, it is possible to relax constraints requiring strict positivity of local priority and hysteresis switching constants. Relaxing these constraints allows the adaptive system to reach optimality which implies the performance improv...

In the quest for novel, scalable and energy-efficient computing technologies, many non-charge based logic devices are being explored. Recent advances in multi-ferroic materials have paved the way for electric field induced low energy and fast switching of nano-magnets using the magneto-electric (ME) effect. In this paper, we propose a voltage driven logic-device based on the ME induced switchin...

Highlighting the dominance & supremacy of CMOS digital logic design over its counterparts & further coming up with a unique solution to minimize the power losses prevalent in switching implementations using CMOS, this brief introduces a novel SDLC (Switching-DiodeInductor-Capacitor) design. It presentsa design which in ideal case may lead to a circuit capable of performing logic operations with...

Pulse-width modulated (PWM) adjustable frequency drives (AFDs) are extensively used in industries for control of induction motors. It has led to significant advantages in terms of the performance, size, and efficiency but the output voltage waveform no longer remains sinusoidal. Hence, overshoots, high rate of rise, harmonics and transients are observed in the voltage wave. They increase voltag...

Dynamic CMOS logic circuits are used in high performance VLSI chips in order to achieve very high system performance. These circuits requires less number of transistors as compare to CMOS logic circuits Dynamic logic circuits are much affected by noise as compared to static CMOS circuit. This is due to the fact that dynamic logic circuits have lower value of switching threshold voltage, which i...

| In designing today's mobile embedded systems such as cellular phones and PDAs, power consumption is an important design constraint. In a CMOS circuit, switching activity accounts for over 90% of total power dissipation. In this paper, we describe a method of encoding opcodes for low-power instruction fetch by reducing the switching activity from the instruction fetch logic. To reduce the swit...

In this paper, the author proposes a sensorless direct torque control (DTC) of an induction motor (IM) fed by seven-level NPC inverter using artificial neural networks (ANN) and fuzzy logic controller. Fuzzy PI controller is used for controlling the rotor speed and ANN applied in switching select stator voltage. The control method proposed in this paper can reduce the torque, stator flux and to...
