  • Patent number: 9431919
    Abstract: A biomedical implant is provided for simultaneously generating multiple voltages for digital and analog circuits. Two AC voltages induced from an external single AC source located externally to the biomedical implant are used as input to a multi-voltage rectifier. The multi-voltage rectifier has a rectifier circuitry for simultaneously generating: (i) both low positive and negative voltages and (ii) both high positive and negative voltages. A startup circuitry is designed to stabilize both low positive and negative voltages prior to stabilizing both high positive and negative voltages. A timing control circuitry is used to prevent reverse leakage currents from loading capacitors to input for efficiency enhancement. The biomedical implant, by virtue of the multi-voltage timing control rectifier, achieves high power transfer efficiency greater than 85%.
