摘要： Certain aspects of the present disclosure generally relate to a semiconductor variable capacitor, and techniques for fabricating the same, implemented using a threshold voltage implant region. For example, the semiconductor variable capacitor generally includes a first non-insulative region disposed above a first semiconductor region, a second non-insulative region disposed above the first semiconductor region, and a threshold voltage (Vt) implant region interposed between the first non-insulative region and the first semiconductor region and disposed adjacent to the second non-insulative region. In certain aspects, the semiconductor variable capacitor also includes a control region disposed above the first semiconductor region such that a capacitance between the first non-insulative region and the second non-insulative region is configured to be adjusted by varying a control voltage applied to the control region.

摘要： A wireless power transfer system may include a primary resonator and one or more secondary resonators. At least one of the secondary resonators lie in overlapping relation to the primary resonator. An electromagnetic (EM) field generated by the primary resonator can couple to the secondary resonators, thus inducing current flow in the secondary resonators. EM fields generated by the secondary resonators interact with the EM field from the primary resonator to produce a resultant EM field.

摘要： A multi-level rectifier is presented that is suitable for use at high frequencies, including into MHz range such as in the 6.78 MHz band used for wireless power transfer. To maintain the proper timing or switching waveform when operating at high frequencies, a feedback loop is used. The rectification circuit includes a multi-level waveform generator circuit that generates a multi-level control waveform from the input waveform and an indication of its current. The multi-level control waveform is maintained in phase with the input waveform. A control signal generation circuit receives the multi-level control waveform and generates control signals corresponding to levels of the multi-level control waveform. A synchronous rectifier receives the input waveform and includes a plurality of switches to provide an output voltage generated from the input waveform. The switches are coupled to receive the control signals and the output voltage is a function of the multi-level control waveform.
