Abstract

Apparatus and methods for supplying power to electronic devices such as portable electronic devices for x-ray fluorescence analysis are described. The apparatus is able to operate at the high frequencies that can be detecting and analyzing certain taggants without the attendant cost and size limitations, by using small, low voltage components (1...M). Working at such higher frequencies while using smaller components allows for faster switching times and higher efficiency, as well as smaller sizes and decreased costs.
