Abstract: A package includes a mounting plate having a first part able to dissipate heat and a second part able to transmit and/or receive electrical signals. A cladding houses a first electronic chip and second electronic chip. The first electronic chip has a first semiconductor substrate (giving off, in operation, a first quantity of heat) mounted to the first part of the mounting plate and electrically connected by wires to the second part of the mounting plate. The second electronic chip has a second semiconductor substrate (giving off, in operation, a second quantity of heat) mounted to an interposer support including an interconnection network. An array of connection balls interconnects the interposer support to the first part of the mounting plate and the second part of the mounting plate. The first and second semiconductor substrates are different.

Abstract: A phase change memory cells including a memory element or a threshold device is read using a read current which does not threshold either the memory element or the threshold device in the case of both a set and a reset memory element. As a result, higher currents may be avoided, increasing read endurance. A sensing circuit includes a charging rate detector coupled to a selected address line and sensing a rate of change of a voltage on the selected address line.

Abstract: An input memory of an LDPC decoder is loaded with data corresponding to an LDPC frame to be decoded and including N LLRs, of which K are information LLRs and N?K are parity LLRs. At least one stream is formed of binary words of a first type, each corresponding to multiple information LLRS, with the aid of a serial/parallel conversion module, and at least one stream is formed of binary words of a second type, each corresponding to multiple parity LLRs, with the aid of a row/column interlacing device comprising a two-dimensional first-in first-out ring buffer. The first memory accesses are made in page mode in order to write the binary words of the first type to a first zone of the input memory, and the second memory accesses are made in page mode in order to write the binary words of the second type to a second zone.

Abstract: A routing block using a switch with a pulsed serial link. An input of a routing block is supplied with an information signal. The routing block has multiple outputs. The information signal includes a first edge and a second edge on a single line. The first and second edges are separated by a time period. One of the first and second edges represents information conveyed by the signal. The other one of the first and second edges provides timing information. The information signal controls the routing block to select one of the multiple outputs and the transferring the signal to said selected one of said multiple outputs. Depending on the number of bits of information transmitted in each pulse and the number of switches controlled by the control information, the decoded control data will include at least one bit outputted serially to a control signal generator block.

Abstract: An optical sensor includes an infra red LED, a photodectector and a lock in charge amplifier. The photodetector passes charge to a feedback capacitor of the charge amplifier following an illumination cycle during which the LED is emitting and also following an illumination cycle during which the LED does not emit. An amplifier presents an output indicative of the difference between the charge generated at the photodectector during the illuminated and non-illuminated cycles.

Abstract: A receiver that can receive several initial signals modulated in a same initial frequency band and/or distinct initial frequency bands and generate a signal modulated in a transmission band to be transmitted on a coaxial cable, comprising a selector that can select several signals from among the received signals; for each selected signal, a mixer capable of transforming the selected signal into a signal at least partly in the transmission band, and a filter capable of extracting from the transformed signal a signal associated with a portion of the transmission band from among several at least partly distinct portions of the transmission band; and means for forming the signal modulated in the transmission band from signals associated with the transmission band portions.

Abstract: A circuit device is provided for driving an AC electric load, of the type inserted between a terminal of an AC power supply line and a terminal of the electric load to be driven and including a generator of PWM signals to be transferred to the load. This circuit is an AC/AC converter adapted to power supply the load from any level of the power supply line sinusoid and comprising first and second voltage driven switches, the first switch to power supply the load and the second switch to enable loop-back of the current. The switches always operate in a complementary manner, i.e., when the first switch is on, the other is off, and vice versa.
