摘要： 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.

摘要： The invention relates to an Electromagnetic Interference (EMI) filter circuit (Fa) for suppressing a Line Conducted Interference (LCI) signal. The EMI filter circuit (Fa) comprises a filter inductance (Lo) to carry a supply current (Isup) between a supply voltage (Vsup) and a load (L). The EMI filter circuit (Fa) further comprises an active circuit (Ca), arranged in parallel with the filter inductance (Lo). The active circuit (Ca) comprises a sensing circuit (Mm) to sense the LCI signal and further comprises a suppressing circuit (Ms) to suppress the LCI signal. In an embodiment of the active EMI filter circuit (Fa), the active circuit (Ca) comprises a negative inductance generating circuit to create a negative inductance value. Selecting the negative inductance generating circuit to create an inductance value (Lca) larger than the inductance value of the filter inductance (Lo) creates a resulting inductance (Lr) which is higher compared to the inductance value of the filter inductance (Lo). In one embodiment, the negative inductance generating circuit comprises a negative impedance converter.

摘要： In an electronic inductor circuit, an operational amplifier drives the base of the electronic inductor transistor, and receives negative feedback from the emitter of the transistor. The transistor and operational amplifier combine to form a voltage-controlled current source (VCCS) with respect to the loop current. A voltage divider connected across the rectified Tip and Ring voltage (or another node of the circuit at an equivalent voltage) provides a DC reference to the positive input of the operational amplifier, so that the line current automatically increases with an increase in line voltage. A capacitor couples the transmit signal driver to the positive input of the operational amplifier. This electronic inductor circuit can be driven using a low voltage supply and provides sufficient linearity for high-speed modem applications.
