摘要： Disclosed is a current sensor (600) that senses current flow in a conductor (604) by coupling a first magnetic field generated by the conductor to a sense element (602). The current sensor includes a shield (700) including a first material (702a,702b) that sandwiches the sense element to define a stack and a second material (704a,704b) that sandwiches the stack. The shield is configured to generate a second magnetic field, responsive to a third magnetic field external to the current sensor that opposes the third magnetic field. The shield is further configured to prevent production of a magnetic field that opposes the first magnetic field generated by the flow of current in the conductor.

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. Depending on the amplitude of the input waveform, the rectifier can be operated in different modes. For lower input levels, the rectifier acts as a voltage doubler. For higher input levels, the impedance of the rectifier can be varied based on the input level. The rectifier is a synchronous rectifier with a front section and a back section, where the impedance is varied by changing the phase of the control signal of the back section relative to that of the front section.

摘要： Resonant rectifier topologies are described for tuning the rectifier so that it performs from an electromagnetic interference (EMI) point of view, while maintaining the voltage regulation at the output that a series tuned rectifier would maintain. Examples include a an inductor of a receive coupler and a rectifier connectable to drive a load, along with first and second filter elements that are each configured to provide an impedance inversion function in a frequency band and that are connected in series between the inductor of a receive coupler and rectifier. In one set of examples, both filter elements are implemented as pair filters, while in other examples the first filter element includes the inductor of a receive coupler in parallel with a capacitance connected to ground.
