<p>In a first aspect, the invention provides to a device comprising a substrate and an electrical conductor arranged between two terminals (A, B) and shaped for forming an inductor comprising at least two loops (1, 2) and arranged such that, at least locally, the far field is reduced. This arrangement results in an inductor which radiates a smaller magnetic field, also referred to as reduced EMI, which results in less noise generated in other inductive parts of an electronic circuit or system. The invention further provides in an advantageous embodiment proper balancing of the parasitic resistance and capacitance. By doing so the physical mid-point of 8-shaped inductors becomes the electrical mid-point (MP) which is beneficial when the inductor is used in a circuit. In a second aspect the invention provides an electronic system comprising the device according to the invention, wherein the electronic system comprises an LC-based voltage-controlled oscillator comprising the inductor, the electronic system being one of a group comprising: a multi-channel TV-receiver, a full-duplex transceiver, and a co-banding system. All these systems benefit from the symmetrical properties of the inductor. The better far-field compensation leads to a smaller VCO pulling effect which leads to a better performance of the system.</p> |
