Abstract: An inductance structure arranged on a semiconductor substrate, including an inductance and a conductive plane arranged between the inductance and the substrate. The conductive plane is formed of several separate conductive elements, the connection of which is performed by conductive tracks connecting at least one conductive element to a contact point M of the conductive plane. Each of the conductive tracks is arranged so that the resultant of the electromotive forces induced in said conductive track by the inductance is substantially null.

Abstract: The present invention relates to a multiplexer with 2 inputs receiving periodic signals (S1 to S2 ) which differ in phase with respect to one another, which multiplexer is controlled in such a way as to switch from a current input signal (Si) to a next input signal (Si+1) by activating a switching signal (O), the next signal (Si+1) having a 360@/2 phase lag with respect to the current signal (Si). According to the invention, means are provided for synchronising the switching signal (O) with an edge of the next input signal (Si+1).

Abstract: Integrated circuit inductance structure comprises: silicon substrate (2); planar winding(s) of a conductive track (1); resistive layer (11), unetched and under the winding; dielectric layer (3) between the winding and the resistive layer; and discontinuous conductive sections (12) individually parallel to a portion of the winding which is the closest and electrically connected to ground and to the resistive layer. Preferred Features: The discontinuous conductive sections (12) are out of true with the winding. Each conductive track (1) is located as near as possible to the nearest portion of the winding. Each portion of the winding is connected to several conductive sections (12). The conductive sections (12) are produced in the same metallic level as the conductive track (1) forming the inductance. The resistive layer has a level of doping of 10 to 10 atoms/cm , preferably 10 atoms/cm . The conductive sections (12) are connected to a contact point by several conductive tracks. Each conductive track is positioned such that the resultant of the electromotive forces induced by the inductance is substantially zero.

Abstract: The quadrature oscillator comprises four identical cells each providing 90 degrees of phase shift, and the output of each cell is supplied to the input of the following cell. Each cell includes a current amplifier (Q') and a parallel resonant circuit inductive capacitance (L1,C1). A feedback arrangement is included in each cell, so that a fraction of the capacitive output current provides a 90 degree phase shift between quadrature outputs.
