  • Patent number: 6999325
    Abstract: A current/voltage converter arrangement is proposed, in which a first switch device (T1) with a first diode (TD1) is provided between a first input terminal (TE1) of a primary side (TP) of a transformer device (T) provided and a first input terminal (E1) of an input region (E), in which a second switch device (T2) with a diode (TD2) is provided between a second input terminal (TE2) of the primary side (TP) and a second input terminal (E2) of the input region (E).

  • Patent number: 6791303
    Abstract: A voltage stabilization circuit is configured between two signal lines. Each of the signal lines carries a signal, and an interference signal is superimposed on at least one of the signals. The voltage stabilization circuit includes an amplifier circuit that provides an anti-phase signal obtained as an amplified difference between the interference signal and a reference signal. The anti-phase signal has a phase that is opposite the phase of the interference signal. The configuration further includes a matching circuit, which is connected in series with the amplifier circuit, and which generates a compensation signal from the anti-phase signal and superimposes the compensation signal on the signal that is superimposed with the interference signal.
