Abstract: An elementary electrical resonator which includes a ribbon conductor forming a flat loop with at least one turn, the conductor having ends which form two parallel segments. The resonator further includes a conducting bridge which forms an arch straddling the two parallel segments of the ribbon conductor wherein opposing surfaces of the arch and the parallel segments form a capacitor. A part of the bridge is capable of being displaced with respect to the parallel segments under the action of a control signal so as to cause the capacitance of the capacitor and therefore the tuning frequency of the resonator to vary.

Abstract: Conducting bridges (21-23) form an arch straddling parallel segments (3,4) whose ends are formed from ribbon conductor that forms a flat loop (16) with a turn. The opposing surfaces of the arch and segments forms a capacitor. A portion of the bridge is displaced with respect to the segments of the loop, under the action of a control signal, to vary the capacitance and tuning frequency of the resonator.

Abstract: The micro-inductance or micro-transformer has a metallic coil with a magnetic core (4) having a ferromagnetic material strip (12). The center has a supplementary strip (13) in ferromagnetic material with a separation layer (14) in non-magnetic material. The non-magnetic material thickness is such that the two ferromagnetic strips are coupled anti-ferromagnetically.

Abstract: The microcomponent manufacture technique has a substrate etched with a number of channels. Copper is deposited by electrolys in the channels and planed flat. A central section (12) is deposited above the segments (7). The central section is then etched for arch sections, each arc connected to an adjacent segment and forming a spiral winding.

Abstract: An inductive component (1) comprises a quartz substrate (2) and a planar inductor coil of copper strip (3) of specified thickness. A novel inductive component (1) comprises a quartz substrate layer (2) and a planar inductor formed of a spirally wound copper strip (3) of greater than 10 mu m thickness. Independent claims are also included for the following: (i) an integrated transformer comprising a quartz substrate (2) and two planar inductor coils which are wound within one another and which are formed of copper strip (3) of greater than 10 mu m thickness; and (ii) an IC associated with the above inductive component or integrated transformer mounted by means of conductive spacer elements which provide electrical connections between IC connection pads and connection terminals of the inductive component or integrated transformer, the inductive component or integrated transformer being oriented with respect to the IC such that its face including the inductors faces the IC. Preferred Features: The strip is about 30 mu m thick. A polyimide layer is provided between the inductor (3) and the substrate (2) and within the strip segment (8) connecting the coil center (9) to the strip end (10) forming a connection terminal. The strip is coated with a gold layer on its surfaces other than those in contact with the substrate or the polyimide layer and the spaces between the facing surfaces of adjacent windings is free from any material. The strip forms a circular spiral or two parallel series-connected spirals, the spiral nearest the substrate being embedded in a polyimide layer which is covered with a silica barrier layer. Spacer elements, of height close to the strip thickness, are mounted on the connection terminal-forming ends of the strip and have a cylindrical shape with a diameter of about three times their height.
