Abstract:
A radio frequency noise reduction device and methods of operation are presented. The radio frequency noise reduction device identifies radio frequency noise on an isolated power plane of an electronic apparatus and generates an electrical signal that is injected into the isolated power plane and cancels the identified radio frequency noise. The generated electrical signal matches the frequency spectrum and amplitude of the identified radio frequency noise but the phase of the generated electrical signal is shifted by 180 degrees from the identified radio frequency noise.
