Feedback refers to a core concept in circuit design and control theory, used to stabilize amplifiers and control system ...
Abstract: Power amplifier (PA) is the core device for dc-RF conversion in wireless power transfer (WPT) system. However, the drain efficiency (DE) of PA decreases significantly due to the load ...
Abstract: A novel class-E power amplifier (PA) using a current-injection (CI) technique is presented in this letter. An auxiliary current source, which injects the current into the load during each ...
