Continuous advancements in integrated circuit design and the constant development of a diverse set of computing applications, paved the way for versatile mobile devices that we use on daily basis. The dependency of these devices on battery as the main power source imposed strict constraints on the energy consumption of applications that run on these mobile devices. In this paper, we present a c...

GeneticFPGA is a Java-based tool for evolving digital circuits on Xilinx XC4000EXTM and XC4000XLTM devices. Unlike other FPGA architectures popular with Evolutionary Hardware researchers, the XC4000 series architectures cannot accept arbitrary configuration data. Only a small subset of configuration bit patterns will produce operational circuits; other configuration bit patterns produce circuit...

Large zero-sequence current is not a new phenomenon for cable bus duct systems; the question what influences its magnitude. It was found that currents were circulating between different circuits in system and they being generated by induction phases same route. determined could be greatly reduced twin circuit symmetrical configuration of cables. However, four-circuit system, no significant redu...

In this paper, a novel single-port five-transistor (5T) Static Random Access Memory (SRAM) cell and associated read/write assist is proposed. Amongst them, a word line suppression circuit is to provide a voltage of the respective connected word line to be lower than the power supply voltage VDD, as such the read/writeability of the cell can be improved and the half-selected cells disturbance ca...

Commonly, the magnetic component designer focuses the design on the performance of the magnetic component without a detailed analysis of the whole circuit. However, a complete design process should cover different stages, from the analytical design to the circuit simulation using accurate models. This paper presents a design example where it is highlighted the importance of designing inductors ...

This paper represents a novel second harmonic power combining oscillator using mutually synchronized Gunn diodes embedded on slot line resonators. A both-sided MIC technology is adopted in the oscillator. The oscillator consists of Gunn diodes, slot line resonators and microstrip lines. By embedding Gunn diodes on slot line resonators, desired harmonic RF signal can be generated very easily. Th...

In this paper, a new neuronal circuit, based on the spiking neuronal network model, is proposed in order to detect the movement direction of dynamic objects wandering around cognitive robots. Capability of our new approach in bidirectional movement detection is beholden to its symmetric configuration of the proposed circuit. With due attention to magnificence of handling of blocking problems in...

In this paper, a novel single-port five-transistor (5T) Static Random Access Memory (SRAM) cell and associated read/write assist are proposed. Amongst them, a word line suppression circuit is to provide a voltage of the respective connected word line to be lower than or equal to the power supply voltage VDD, so that the read/write-ability of the cell can be improved, and the half-selected cells...

Evolvable hardware (EHW) is a new technology, which was discovered at intersection of artificial intelligence and the circuit design. Unique hardware architecture is searched for each task. The circuit connection is subject of evolution and the function of such circuit can adapt to dynamic changing environment. Genetic algorithm is used to simulate evolution – its chromosomes encode potential s...

Circuit breakers (CBs) are the main protection devices for both alternating current (AC) and direct current (DC) power systems, ranging from tens of watts up to megawatts. This paper reviews the current status for solid-state circuit breakers (SSCBs) as well as hybrid circuit breakers (HCBs) with semiconductor power devices. A few novel SSCB and HCB concepts are described in this paper, includi...
