Figure 1: Comparison between conventional and PT-symmetry-based wireless power transfer schemes as the source–receiver resonant coupling rate κ varies as a function of transfer distance d. Figure 3: ...

Because of the shell arrangements of electrons in various atoms and molecules, some substances are quite good at allowing a few electrons to move about freely (e.g., copper, silver, gold, aluminum), ...

A ripple-generating circuit is usually needed to ensure stability of constant-on-time (COT) controlled buck converters. Different values of the ripple generating circuit can have direct impacts on ...

This article explains the switching behavior of power MOSFETs in practical application circuits and shows the reader/designer how to choose the right device for the application using the ...

Power is the energy transferred per unit time. Power is measured in watts (W), energy in joules (J) and time in seconds (s). 1 W = 1 J/s (1 watt is 1 joule per second.) Electrical power can be ...

For battery-powered circuits, it is easy to build an ultralow-current crystal oscillator designed around a 32.768-kHz crystal. This crystal is common for real-time-clock circuits. Because these ...
