  • Patent number: 11501093
    Abstract: In an embodiment, a method of managing an output power delivered by an antenna of a NFC apparatus includes: providing a matching circuit with a first tuning capacitive network coupled in series between a NFC controller and the antenna and with a second tuning capacitive network coupled to the NFC controller and the antenna and to a reference terminal, wherein the first or second tuning capacitive network has a variable capacitive value; determining tuning capacitive values of the first tuning capacitive networks to adjust a delivered output power at a desired level; and setting the tuning capacitive values of the first tuning capacitive network to the tuning capacitive values.

  • Patent number: 8063697
    Abstract: A self-oscillating driver circuit comprises a driver stage, a feedforward path which is coupled to an input of the driver stage, and a feedback path which couples an output of the driver stage to an input of the feedforward path. The feedforward path comprises a feedforward filter which is designed as an active filter. In order to prevent an oscillatory state of the driver circuit at an unwanted frequency, it is proposed that an internal state variable of the feedforward filter be monitored and that the feedforward filter be reset if the value of the monitored internal state variable is outside a predefined range.

  • Patent number: 7642877
    Abstract: A self-oscillating pulse-width modulator comprises an input, an output and a control loop. The control loop comprises a forward branch and a feedback loop. The forward branch is connected between the input and the output and comprises a comparator and a delay element. The feedback loop loops back to the input a feedback signal which depends on an output signal present at the output. The phase shift of the open control loop is 180° at the frequency of an oscillation to be generated by the modulator. At least a part of the phase shift is realized in the forward branch by means of the at least one delay element.
