Abstract: The present disclosure relates to a voltage regulation circuit including a first transistor connected between an input of voltage to be regulated and an output of a regulated voltage. A first regulation loop controls the first transistor according to a difference between a reference voltage and a first feedback voltage derived from the regulated voltage. A second transistor is connected in series between the first transistor and the output. A second regulation loop controls the second transistor according to a difference between the reference voltage and a second feedback voltage derived from the regulated voltage. The second regulation loop is active in low and high power regulation modes. A switch circuit forces the first transistor into an on state in a low power regulation mode.

Abstract: The invention relates to a method for serial data transmission, comprising the steps consisting in computing the running disparity (RD) of a bit stream that is being transmitted; when the running disparity reaches a threshold (T), computing a point disparity on a subsequent frame (S) of the stream; if the point disparity has the same sign as the threshold, inverting the states of the bits of the frame in the transmitted bit stream; and inserting into the transmitted bit stream a polarity bit having a state signalling the inversion.

Abstract: An electronic device includes a support board having a mounting face and an integrated circuit chip mounted on the mounting face. An encapsulation block embeds the integrated circuit chip, the encapsulation block extending above the integrated circuit chip and around the integrated circuit chip on the mounting face of the support board. The encapsulation block includes a front face with a hole passing through the encapsulation block to uncovering at least part of an electrical contact. A layer made of an electrically conducting material fills the hole to make electrical connection to the electrical contact and further extends over the front face of the encapsulation block.

Abstract: An analog video signal supply circuit includes a processing circuit that supplies first and second digital video signals. First and second digital-to-analog converters convert digital signals to analog signals. A control circuit controls operation in a first configuration where the first digital video signal is applied to an input of the first digital-to-analog converter and the second digital video signal to an input of the second digital-to-analog converter. The control circuit further controls operation in a second configuration where the first digital video signal is simultaneously applied to the inputs of the first and second digital-to-analog converters.

Abstract: A diode control device include a first terminal for receiving a first power supply voltage and a second terminal for receiving a second power supply voltage. A circuit of the diode control device applies a regulated voltage on the anode of the diode in response to a control voltage. The control voltage is equal to a preset voltage when a reference voltage is less than or equal to zero. Conversely, when the reference voltage is greater than zero, the control voltage is equal to the sum of the present voltage and a difference between cathode voltage of the diode and the reference voltage.

Abstract: A circuit may include an audio amplifier (314) configured to amplify an input signal (SAUDIO) to generate an output signal (SOUT+, SOUT−) suitable for driving a loud speaker (316). A first circuit (318) may be configured to generate a first analog signal (SI) based on a current level drawn by the loud speaker (316), and a second circuit (320) may be configured to generate a second analog signal (SV) based on a voltage supplied across the loud speaker (316). A third circuit (322, 312) may be configured to generate a third analog signal (RESIDUE) based on the difference between the first and second analog signals, and modify the input signal (SAUDIO) based on the third analog signal.
