  • Patent number: 9490725
    Abstract: Examples of multi-stage programmable rectifiers are provided herein. Each rectifier stage can include a first transistor and a switch connected to the first transistor. A threshold voltage of the first transistor can be programmed through selection of one of a plurality of voltages available at the switch. Each rectifier stage can also include a second transistor that can be connected in series with the first transistor. An output capacitor can be connected to the second transistor at an output of the rectifier stage. The plurality of voltages provided at the switch allows the threshold voltage of the first transistor to be adjusted in either a positive or negative position to increase efficiency of the rectifier. A calibration process can be used to identify the position of each switch in the rectifier stages that results in the highest efficiency or rectifier output voltage.
