Abstract: Methods and devices for adjusting a read threshold voltage of bitlines are provided. One such method includes adjusting a read threshold voltage of bitlines coupled to memory points of a memory circuit. The read threshold voltage is initially set to a first value. First data are written in the memory points and second data are read from the memory points. The second data are compared to the first data, and the threshold voltage is decreased by a second value in response to a comparison error of one of the second data with the corresponding first data.

Abstract: A method for controlling a signal envelope shape of modulation pulses in a driver of a wireless transmitter includes supplying a first voltage to the driver during a non-modulated state, supplying a second voltage configurable by a configurable modulation index value to the driver during a modulated state, switching between the non-modulated state and the modulated state comprising setting the modulation index value to configure the second voltage level at the same level as the first voltage and then switching between supplying the first voltage to the driver and supplying the second voltage to the driver, and filtering to a limited bandwidth the variations of the second voltage resulting from configuring the modulation index value.

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: An electronic envelope detection circuit includes an input signal detecting circuit having at least one MOS transistor configured to receive a radiofrequency input signal and to deliver an internal signal on the basis of the input signal. The biasing point of the at least one transistor is controlled by the input signal and a control signal. A processing circuit that is coupled to the input signal detecting circuit is configured to deliver a low-frequency output signal on the basis of the internal signal and further deliver the control signal on the basis of the output signal. In operation, the value of the control signal decreases when the average power of the input signal increases, and vice versa.

Abstract: Requests are received by a routing circuit. A plurality of first round-robin arbitration circuits are coupled to the routing circuit. There are as many first round-robin arbitration circuits as there are possible priority levels for the requests. The routing circuit operates to transmit each received request to a number of first round-robin arbitration circuits determined according to the priority level of the request. A second round-robin arbitration circuit has inputs respectively connected to the outputs of the first round-robin arbitration circuits.

Abstract: An attenuator having an impedance that is controllable by a first setpoint signal is coupled to a transmission line. A matching circuit having an impedance that is controllable by a second setpoint signal is also coupled to the transmission line. A transformer circuit block also coupled to the transmission line has a complex impedance. A control circuit sets the first and second setpoint signals so as to control a conjugate impedance relationship between the variable impedances presented by the attenuator and matching circuit relative to the complex impedance of the transformer circuit.

Abstract: A method is provided for controlling the matching of an antenna to a transmission path. The transmission path includes an amplifier stage coupled at an input or at an output to the antenna and to a resistive load. The method includes performing a checking phase by measuring a first current temperature at or in proximity of the antenna and a second current temperature at or in proximity of the resistive load, triggering a matching of the impedance seen at the input or at the output of the amplifier stage in the presence of a first condition involving the first and second current temperatures, and then stopping the matching of the impedance in the presence of a second condition involving the second current temperature.
