An overview of recent progress in the research and development of microelectromechanical devices for use in wireless communication sub-systems is presented. Among the specific devices described are tunable micromachined capacitors, integrated high-Q inductors, low loss micromechanical switches, and micro-scale vibrating mechanical resonators with Q’s in the tens of thousands. Specific applicati...

A segment of an existing Belgian medium-voltage distribution system is used to study the power quality and voltage stability with different distributed generation (DG) technologies (Figure C16.1). The system includes one transformer of 14 MVA, 70/10 kV and four cable feeders. The primary winding of the transformer is connected to the transmission grid and can be considered as an infinite node. ...

In deep-submicron technologies the primary component of delay is shifting from logic gates to the interconnect network. Buses can no longer be considered as a set of independent lines that don’t interact. A more appropriate model would treat the bus as a distributed system, where a transition on a line would affect adjacent lines as well. However, the transitions on the buses can be grouped int...

This paper presents a novel methodology for IC speed-up in 32 nm FinFET. By taking advantage of independently controlling two gates of IG-FinFET, we develop the boosting structures that can improve the signal propagation on interconnect significantly. Furthermore, the circuit area and power dissipation issues are also taken into account. With the addition of boosting path, the full booster can ...

We have characterized the ON state DC electrical resistivity and OFF state capacitance of GeTeBased RF Switches under direct optical laser excitation. Our tightly-coupled dipole array exhibits performance in excess of 4 to 1 bandwidth over wide-scan angle up to 60 degrees with in-band rejection capability using reconfigurable baluns. Integration of optically-controlled GeTe-Based RF switches at...

Globally, governments are mandating a switch from internal combustion engine (ICE) technology to electric-drive vehicles in 100s of millions combat climate change. For example, on 29 June 2022, the European Union...

Semiconductor power modules are the key hardware components of a traction inverter. It drives motor speed and torque, managing energy exchange from battery to viceversa. The increasing demand for electric hybrid vehicle requests high performance modules. Power semiconductor devices based on wide band gap compound, like silicon carbide (SiC), have excellent electrical properties in terms on-stat...

This paper describes the integration of power electronic and energy storage applications in distribution substations. Auxiliary circuits must provide motor-driven power switches, protection relays and telecontrol systems with constant power supply, thus minimising power outages and their negative effects on consumers. Requirements on the apparatus are proportional to the distributed voltage lev...

TENS (Transcutaneous Electrical Nerve Stimulator) is a therapeutic device used to deliver electric current through one’s skin. As the device is used on the human body, safety concern becomes a matter that needs special attention. One option for electrical safety is testing whether the electrode has attached properly to the skin. The test is done in the interval of the simulator pulse. This opti...
