The choice between a linear power supply such as this one and a switching design for high quality audio is by no means clear-cut, and may be something we’ll consider in our Know Audio series.

This repository include design files, shematic and single-layer PCB film for DIY high quality linear U/I regulater power supply.

The efficiency of linear RF power amplifiers in which transistors are operated as dependent ... The efficiency can be improved if the ratio of the amplitude of the RF power amplifier to its power ...
