Abstract: The invention relates to a method and a device, which provide a particularly cost-effective, space-saving solution for supplying power to a consumer (current sink RL) via two data line pairs of a local network (LAN). The invention is characterised in that it uses a circuit arrangement comprising two electronic reactance coils (D1/D2, D3/D4) per data line pair to tap a supply voltage that is made available by a voltage source. To obtain a self-symmetry for the circuit arrangement, the two base connections and the two output connections of the electronic reactance coils (D1/D2, D3/D4) are interconnected.

Abstract: Disclosed is an electronic decoupling inductor for applications in actuator sensor interface networks. Said electronic decoupling inductor represents a subassembly that is independent from the actuator sensor interface IC (AS-I IC), is designed as a bipolar gyrator circuit without reference to ground, and comprises a base-controlled transistor, a capacitor with a charging resistor for influencing the current rise through the transistor when current flows, a voltage divider for adjusting the operating point of the transistor, and an appropriate RC constant of the base-emitter resistor and capacitor in order to block the high-frequency data signals as well as propagation of current changes on the AS interface bus (AS-I bus). The inventive electronic decoupling inductor directly replaces a wound inductor.

Abstract: A capacitance multiplier includes a self-biasing active load for generating a stable bias voltage without a separate current bias. In addition, the capacitance multiplier includes a cascode load within a multiplying section for increasing the output resistance and in turn the charging/discharging efficiency. Furthermore, the capacitance multiplier is implemented with a plurality of multiplying paths to reduce effects of noise for more stable generation of the multiplied capacitance.

Abstract: A node power isolator for connecting a node of a two conductor transmission line network such as a twisted pair line (20, 22) to the network so as to enable the DC powering of the node from the network itself without significantly diminishing the signal levels on the network or interfering with the node's ability to receive signals form or transmit signals on the network. Current flow through the power isolator (26a, 26b) is through a transistor (34) coupled in series with each transmission line (20, 22) to node connection, with the base to emitter voltage of the transistor (34) clamped to be substantially constant at the signalling frequencies of interest, either directly by a capacitor (40) connected there across, another circuit having a capacitor (48) connected between the base and the emitter of another transistor (42) or both. Various embodiments are disclosed.

Abstract: A frequency and/or phase characteristic control circuit comprising a current multiplier (8) and an operational amplifier (9), the current multiplier (8) containing a pair of diode junctions (Q₄,Q₅) and a transistor (Q₁,Q₂,Q₃) arrangement for differential amplification (10), the operational amplifier (9) having a capacitor (18) connected to the out-of-phase input terminal thereof. The multiplying ratio of the current multiplier (8) is varied so as to control the frequency and/or phase characteristic. This makes the circuit conductive to being implemented in an IC (integrated circuit). This circuit is particularly suitable for use as a circuit that switches the servo circuits of a laser disc player and a compact disc player.
