As the number of Power Over Ethernet (PoE) powered device (PD) applications grows, market pressures are driving designers to lower the cost and complexity of the DC-DC converters that power them, ...

Neural microcircuits consisting of a few neurons and their interconnections are small enough to be understood more completely than larger neural structures, whose complexity quickly becomes ...

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, then reduces the current to save power. Fellow engineer Sanjay R. Chendvankar of Mumbai, India, recently ...

This file type includes high resolution graphics and schematics when applicable. A most critical device in an optical networking system is the laser diode, since it’s responsible for converting the ...
