Abstract
It is described a high efficiency rectification stage using dynamic threshold MOSFET. The idea is to use the input signal to reduce the threshold voltage when the transistor has to be on, and to increase the threshold when the transistor has to be off. This allows reducing both the resistive losses and the leakage current. A matching network allows the generation of a second higher voltage signal to drive the control gates and the bulk, i.e. the wells, of the transistors. Further, a self-tuned front-end is provided to extend the bandwidth of the high-Q charge pump.
