A structure for protecting an integrated circuit connected to first and second rails of a differential link against overvoltages, including: a first bidirectional conducting device, between the first rail and a common node; a second bidirectional conducting device, between the second rail and the common node; and a capacitor between the common node and a low reference potential rail.

Overvoltage protection structure for a differential link

A common-mode filter including two input terminals and two output terminals and, in series between each input or output terminal and the ground, a capacitive element and a first inductive element.

Common-mode filter

The manufacturing of electronic components on individual substrates made of an insulating material includes molding, in a silicon wafer, an insulating material with a thickness corresponding to the final thickness desired for the substrates, manufacturing the electronic components, and removing the silicon from the rear surface of the wafer after manufacturing of the components.

Thin glass chip for an electronic component and manufacturing method

A multi-band inductive circuit in an integrated circuit, including at least two parallel branches respectively including a first inductance and a second inductance in series with a capacitor, the two inductances being coupled to each other.

Integrated bi-band inductance and applications

A mode-switching transformer selective on a band centered on a first frequency, comprising, between a same common mode input/output terminal and respectively one of two differential mode input/output terminals, a high-pass filter with a cut-off frequency smaller than said first frequency, a band-pass filter with a central frequency greater than said first frequency.

Frequency-selective balun transformer

An interface circuit including a galvanic isolation barrier between a transmission line and a user equipment, and a detector for detecting, independently from a transmission, the idle or busy state of the line.

Line take-up detection circuit

The invention concerns a control circuit for controlling a power switch by means of a galvanic insulation transformer, the transformer being produced in the form of planar conductive windings on an insulating substrate () whereon are integrated passive components constituting a high frequency excitation oscillating circuit for a primary winding of the transformer, the transformer substrate being directly mounted on a wafer () whereon is mounted a circuit chip () integrating the power switch.

Integrated switch with RF transformer control

A filter is formed as an integrated circuit by resistive and capacitive elements and includes, for connection to ground, at least two separate pads of a chip designed to be connected individually to at least two separate terminals of a package.

Integrated low-pass or band-pass filter

A one-way switching circuit of the type including a gate tun-off thyristor biased to be normally on, further includes, between the gate and a supply line, a capacitor and a controllable switch connected in parallel.
