Stator faults typically have a significant share amongst the common type of faults in industrial three-phase induction (asynchronous) motors. This paper presents a motor current signature analysis (MCSA)-based diagnostics of the stator winding short circuit fault. This type of fault happens due to the destruction of the turn insulation, and can be very detrimental causing motor shutdown. Instea...

A new method for designing single rail asynchronous circuits is studied. It utilises additional circuitry to monitor the activity of nodes within combinational logic blocks. When all transitions have halted a completion signal is generated. Details of the circuit and design methodology are given and the influence of glitches on the proposed circuit is discussed. Three different levels of granul...

In this paper circuit implementations of cellular processor arrays intended for image processing applications are discussed. It is demonstrated that a departure form the standard CNN model can lead to a significant improvement when processing binary (black/white) images. An asynchronous cellular logic array circuit is presented, which is capable of simulating trigger-waves in an excitable mediu...

This letter studies response of a chaotic spiking oscillator to chaotic spike-train inputs. The circuit can exhibits a variety of synchronous/asynchronous phenomena and we show an interesting phenomenon “consistency”: the circuit can exhibit random response that is identical in steady steady state for various initial values. Presenting a simple test circuit, the consistency is confirmed experim...

Asynchronous circuits are increasingly proposed as an efficient circuit-level solution for Process Variability. Asynchronous circuits are self timed, which gives them the opportunity to be immune against all variability sources including process-variability. Moreover, asynchronous circuits gain interesting properties due to variability in terms of performance and power-consumption distribution....

For high performance designs, dynamic logic techniques have to be considered due to the promising high reachable frequencies. Such a technique is the True Single Phase Clock (TSPC) logic that allows designing circuits with standard cells and high speed potential. However, the disadvantages are a difficult clock tree design and high power consumption. Asynchronous logic has the potential to solv...

Formal verification of asynchronous circuits is known to be challenging due to highly non-deterministic behavior exhibited in these systems. One of the main challenges is that it is very difficult to come up with a systematic approach to establishing invariance properties, which are crucial in proving the correctness of circuit behavior. Nondeterminism also results in asynchronous circuits havi...
