Abstract: In an embodiment, a method for determining the phase shift between a first signal and a second signal includes: delivering the first signal to a first input of a 90° hybrid coupler; delivering the second signal to a second input of the 90° hybrid coupler; determining a first piece of information relating to a power of a first output signal delivered to a first output of the 90° hybrid coupler; determining a second piece of information relating to a power of a second output signal delivered to a second output of the coupler; and adjusting the phase of the second signal until obtaining a calibrated phase for which the first piece of information is substantially equal to the second piece of information, wherein the first and second signals have identical frequencies, and wherein the phase shift between the first signal and the second signal is equal to the calibrated phase.

Abstract: A cell includes a Z2-FET-type structure that is formed with two front gates extending over an intermediate region between an anode region and a cathode region. The individual front gates of the two front gates are spaced apart by a distance that is shorter than 40% of a width of each individual front gate.

Abstract: An optical modulator uses an optoelectronic phase comparator configured to provide, in the form of an electrical signal, a measure of a phase difference between two optical waves. The phase comparator includes an optical directional coupler having two coupled channels respectively defining two optical inputs for receiving the two optical waves to be compared. Two photodiodes are configured to respectively receive the optical output powers of the two channels of the directional coupler. An electrical circuit is configured to supply, as a measure of the optical phase shift, an electrical signal proportional to the difference between the electrical signals produced by the two photodiodes.

Abstract: An embodiment electronic device comprises at least two antennas for transmitting signals, and at least one transmission path, the transmission path including a first coupling stage including a power divider, variable-gain power amplifiers, and a second coupling stage including a power combiner. Each coupling stage includes two inputs and two outputs, the two inputs of the first coupling stage being configured to receive a power input signal. Each output of the first coupling stage is connected to a different input of the second coupling stage via the variable-gain power amplifiers, and each output of the second coupling stage is connected to a different antenna. A controller is configured to control the gains of the variable-gain power amplifiers according to the characteristics of the power input signal, the signals transmitted by the antennas, and the coupling stages.

Abstract: An asynchronous pipeline circuit includes: a first processing stage including a first data latch configured to generate a request signal; a second processing stage downstream the first processing stage and including a second data latch; and a programmable delay line coupled between the first data latch and the second processing stage. The programmable delay line is configured to receive the request signal from the first data latch and to generate a delayed request signal by randomly delaying the request signal on each data transfer from the first data latch to the second data latch.

Abstract: A bipolar transistor includes a collector. The collector is produced by a process wherein a first substantially homogeneously doped layer is formed at the bottom of a cavity. A second gradually doped layer is then formed by diffusion of dopants of the first substantially homogeneously doped layer.

Abstract: A variable-gain amplifier includes two amplification and attenuation branches, and first and a second resistive elements that are coupled between the two branches. Each branch includes a voltage follower stage and a configurable amplification stage. The voltage follower stages are intended to receive a differential signal and are configured to deliver, via the first resistive element, an intermediate differential current signal. The amplification stages are intended to receive the intermediate differential current signal and a digital control word, and are configured to deliver, via the second resistive element, an output differential voltage signal depending on the value of the digital control word.

Abstract: An electronic device includes a module that delivers a positive temperature coefficient output voltage at an output terminal. A thermistor includes a first MOS transistor operating in weak inversion mode and having a negative temperature coefficient drain-source resistance and whose source is coupled to the output terminal. A current source coupled to the output terminal operates to impose the drain-source current of the first transistor.

Abstract: A light sensor includes a first pixel and a second pixel. Each pixel has a photoconversion area. A band-stop Fano resonance filter is arranged over the first pixel. The second pixel includes no Fano resonance filter. Signals output from the first and second pixels are processed to determine information representative of the quantity of light received by the light sensor during an illumination phase in a rejection band of the band-stop Fano resonance filter.
