A 2.4 GHz CMOS RF front-end using for ZigBee application is described. The front-end consists of a low noise amplifier and a down-mixer and uses a 2 MHz IF frequency. A common source with resistive feedback and an inductive degeneration are adopted for a low noise amplifier, and a 20 dB gain control step is digitally controlled. A passive mixer for low current consumption is employed. The RF fr...

In this paper, different routing techniques using decision logic with identity circuit to identify the faulty element in FPGA interconnects are presented. The fault model we use here is stuck-open and resistive-open for interconnects. This technique is implemented in FPGA chips and verified using fault emulation. Failure analysis and the yield enhancement process are done by using high resoluti...

Keeping the synchronization of a grid feeding converter (GFC) with weak during deep voltage sags has been introduced as serious challenge in converter-interfaced renewable energy source-dominated grids. To deal this challenge, simple yet effective solution based on virtual inertia concept is proposed article. This method realized by adding correction term to dc-link controller, which adjusts ac...

A feed forward neural network (FFNN) has been trained to discriminate between power transformer magnetizing inrush and fault currents. The training algorithm used was back-propagation, assuming initially a sigmoid transfer function for the network’s processing units (“neurons”). Once the network was trained the units’ transfer function was changed to hard limiters with thresholds equal to the b...

Fault current limiters (FCLs) can be considered as key elements in power systems using high temperature superconductors. This analysis takes into account the system benefits provided by the introduction of FCLs in various network configurations. New meshing possibilities, alternative grounding method and increase of power transmission are highlighted. It is the desire of most power system utili...

2014 The thermodynamic treatment of equilibrium fluctuations in magnetic systems is discussed and applied to a variety of situations. The spectral density of the magnetic moment or flux are derived for simply-connected bodies (sphere and cylinder) and for multiplyconnected systems (loop and hollow cylinder). The material is considered to be either a normal conductor, a superconductor or ferroma...
