摘要： A system of a power device and a portable device for wireless charging of a battery of the portable device. The power device includes an antenna to receive power adjustment information to increase or to decrease the power of the magnetic field emitted by the antenna of the power device and an antenna exposed to the magnetic field and connected via a matching stage to a rectifier stage. The portable device includes a voltage limiter, to limit the rectified antenna signal, and to provide an input voltage at an input pin of a charger IC. A charge voltage control stage is built to generate the power adjustment information for the power device to increase or to decrease the power of the magnetic field emitted by the antenna of the power device to steer the waste current within an upper limit and a lower limit.

摘要： A digital power amplifier comprises: an integrated circuit (IC2); an adaption circuit of discrete components connected to first and second transmission output pins of an integrated circuit to adapt the output signal and feed a substantial sinusoidal output current with a transmission resonance frequency to an RFID antenna. IC2 comprises a digital control section with N wave-forming contacts to output a digital wave-forming bit combination of N bits with a clock frequency M-times the transmission resonance frequency; N driver blocks each connected with a first contact to one of the wave-forming contacts and N/2 of them connected with a second contact to the first transmission output pin and the other N/2 of them connected with their second contact to the second transmission output pin. The driver blocks provide increments of the substantial sinusoidal output current to the first and second transmission output pins.

摘要： A receiver receives a load modulated analog input signal and outputs digital data detected in the input signal. An in-phase correlator and a quadrature-phase correlator for each of an in-phase component and an quadrature-phase component correlate the in-phase component and the quadrature-component with an in-phase component and a quadrature-phase component of a subcarrier or code clock frequency of the input signal. A combiner combines four output signals of the two in-phase correlators and the two quadrature-phase correlators. A slicer samples an output signal of the combiner at maximum energy levels to output the digital data detected in the input signal.
