has been a fundamental building block of RF circuits since their
inception, allowing energy to be recycled and built up over time.
However, the classic linear resonant circuit shown has the drawback that
it only operates around one resonance frequency. Moreover, as the
efficiency of the resonance increases then the bandwidth around this
frequency drops proportionally. In practice bandwidth is required for
communication and to tolerate detuning or variation at manufacture.
This limits the practical efficiency that is possible.
technology takes a fundamentally new approach to this established
technique and opens up the use of an efficient resonance without the
same bandwidth limitation. Two principles are outlined of the Self
Adjusting Resonance and Dynamic Bandwidth Control that address
detuning/component accuracy and communication bandwidth, respectively. These principles are the basis of our patented
technology, which yields a step change in performance in many RF
