  • Regulated load modulation circuit and method for producing regulated load modulation signaling
    Patent number: 10103585
    Abstract: A load modulation circuit includes a resonator circuit configured to resonate based on a received charging power and produce a resonance output signal based thereon, and a rectifier circuit configured to receive the resonance output signal and convert the resonance output signal to a rectified voltage signal. The load modulation circuit further includes a sensor circuit configured to sense the rectified voltage signal and generate a control signal based on the rectified voltage signal and a target power range associated with a change in conducting power of the load modulation circuit during a load modulation. Lastly, the load modulation circuit includes a controllable current source circuit configured to generate a controlled current based on the control signal, wherein the controlled current modulates a load of the load modulation circuit while concurrently maintaining a change in total conducting power at an output of the rectified circuit within the target power range.
