Abstract: A read signal generator generates read signals to control read operations of a memory array. The read signal generator can be selectively controlled to generate an oscillating signal having a period that corresponds to a feature one of the read signals. The oscillating signal is passed to a frequency divider that divides the oscillating signal and provides the divided oscillating signal to an output pad. The frequency of the oscillating signal can be measured at the output pad. The frequency of the oscillating signal, and the duration of the read signal feature can be calculated from the frequency of the oscillating signal. The read signal feature can then be adjusted if needed.

Abstract: An embodiment driver circuit comprises a power supply pin configured to receive a power supply voltage, and a set of control pins configured to provide a set of control signals for controlling switching of a set of switches of an h-bridge circuit comprising a pair of high-side switches and a pair of low-side switches. The driver circuit comprises control circuitry coupled to the control pins and configured to generate the control signals, and sensing circuitry coupled to the power supply pin and configured to generate a detection signal indicative of the power supply voltage exceeding a threshold value. The control circuitry is sensitive to the detection signal and is configured to generate the control signals to activate one of the pair of high-side switches and the pair of low-side switches and de-activate the other of the pair of high-side switches and the pair of low-side switches.

Abstract: A control circuit for controlling switching operation of a switching stage of a converter includes a phase detector circuit that generates a pulse-width modulated (PWM) signal in response to a phase comparison of two clock signals. A first clock signal has a frequency determined as a function of a first feedback signal proportional to converter output voltage. A first transconductance amplifier generates a first current indicative of a difference between a reference voltage and the first feedback signal, and a second transconductance amplifier generates a second current indicative of a difference between the reference voltage and a second feedback signal proportional to a derivative of the converter output voltage. A delay line introduces a delay in the first clock signal that is dependent on the first and second currents as well as a compensation current dependent on a selected operational mode of the converter.

Abstract: An embodiment method comprises receiving a satellite signal in a tracking channel, generating a set of replicas of a pseudo random noise sequence, comprising a punctual replica and a plurality of replicas that are different in time with respect to the punctual replica over a given time spacing, correlating the received signal with each replica to obtain amplitude correlation values, monitoring the tracking channel to detect a spoofed signal by generating a further plurality of replicas of the pseudo random noise sequence having a respective time spacing greater than the given time spacing, correlating the received signal of the tracking channel with each further replica to obtain further amplitude correlation values, calculating a shape anomaly factor based on the further correlation amplitude values, verifying the shape anomaly factor is greater than a given shape anomaly threshold, and signaling detection of a spoofed signal on the tracking channel.

Abstract: An embodiment method for controlling at least one functionality of an electronic device on the basis of a gesture of a user comprises detecting, by a sensor, a variation of electrostatic charge of the user during the execution of the gesture and generating a charge variation signal. The gesture includes moving at least one foot upward and, subsequently, downward. The method further includes, by a processing unit, acquiring the charge variation signal, detecting, in the charge variation signal, a characteristic identifying the gesture of moving the foot upward, detecting, in the charge variation signal, a characteristic identifying the gesture of moving the foot downward, and controlling the functionality of the electronic device only in the event that both the first and the second characteristics have been detected.

Abstract: A method is provided for controlling an electronic apparatus on the basis of a value of a lid angle between a first hardware element accommodating a first magnetometer and a second hardware element accommodating a second magnetometer. The method includes acquiring, through the magnetometers, first signals representing an orientation of the hardware elements. A calibration parameter indicative of a condition of calibration of the magnetometers is generated on the basis of the first signals. A reliability value indicative of a condition of reliability of the first signals is generated on the basis of the first signals. A first intermediate value of the lid angle is calculated on the basis of the first signals. A current value of the lid angle is calculated on the basis of the calibration parameter, of the reliability value, and of the first intermediate value, and the electronic apparatus is controlled on the basis of the current value.
