The celebrated ‘555’ IC was originally developed as a timer device, but over the years this golden oldie has been used in all sorts of other applications, including some never imagined by its ...

Wireless power transfer (WPT) working at megahertz (MHz) is now being widely considered a promising candidate for the midrange transfer of a medium amount of power. Efforts have been made to build ...

Class D amplifier is rarely reported to be broken when it is operating with a fluctuating load. This is because excessive voltage or current is imposed on the transistor of the class D amplifier.
