  • Electronic circuit and method for determining an impedance
    Patent number: 9188613
    Abstract: An electronic circuit is arranged in an external programming device and is used for contactless programming of a circuit to be programmed. The electronic circuit has a series resonant circuit that includes a transmitter coil and a capacitor. The transmitter coil of the series resonant circuit is used for inductive coupling to a receiver coil in the circuit to be programmed. For the purpose of evaluating the impedance that actually exists in the circuit to be programmed, there is provided a device for determining the value of the impedance from a phase difference between the control voltage of the series resonant circuit and the capacitor voltage of the series resonant circuit.
