  • Publication number: 20220345525
    Abstract: The present disclosure is directed to a device and method for generating and transmitting a TDM signal including both raw data and processed data. The device includes a sensor having a time division multiplexing (TDM) interface. The TDM interface transmits both raw data and processed data in a single TDM signal by reserving one or more slots inside a TDM frame for transmission of the processed data. The sensor also embeds additional information inside a data stream of raw data by repurposing one or more of values of the raw data as an exception code, flag, or another type of notification. The device is also enabled to transmit data, and disabled when not in use in order to conserve power.

  • Publication number: 20220315416
    Abstract: The sensor is configured to provide a digital output signal and has a digital detector, which is configured to detect a physical quantity and generate a conditioned digital signal indicative of the detected physical quantity; and a rate modification stage, configured to receive the conditioned digital signal and a group of parameters, the group of parameters comprising an interpolation factor and a downsampling factor, and to provide the digital output signal. The rate modification stage has an interpolator and a decimation element. The interpolator is configured to receive and to upsample the conditioned digital signal based on the interpolation factor and to provide an interpolated signal. The decimation element is configured to downsample the interpolated signal based on the downsampling factor, thereby generating the digital output signal.

  • Publication number: 20220321318
    Abstract: A sensor includes detection circuitry and control circuitry coupled to the detection circuitry. The detection circuitry generates a detection signal indicative of a detected physical quantity. The control circuitry, in operation receives the detection signal and a frequency-indication signal, and generates a trigger signal based on the frequency-indication signal and a set of local reference signals. The sensor generates a digital output signal and a locking signal based on the trigger signal and the detection signal. The generating the digital output signal includes outputting a sample of the digital output signal based on the trigger signal. The locking signal is temporally aligned with the digital output signal.

  • Patent number: 11199422
    Abstract: A demodulator for demodulating the in-phase component of an input signal which is in-phase and quadrature modulated. The demodulator includes a register storing a phase calibration value and a temperature sensor that performs a plurality of temperature sensings. A compensating stage generates for each temperature sensed a corresponding first sample on the basis of the difference between the sensed temperature and a calibration temperature and a compensation function indicative of a relationship existing between the phase of the input signal and the temperature. A combination stage generates a plurality of second samples, each second sample being a function of the phase calibration value and a corresponding first sample. A generating stage generates a demodulating signal having a phase which depends on the second samples and a demodulating stage demodulates the input signal by means of the demodulating signal.

  • Patent number: 10921164
    Abstract: A MEMS sensor generates an output multiscale reading signal supplied to a full scale adjustment stage. The full scale adjustment stage includes a signal input configured to receive the reading signal, a saturation assessment block, and a full scale change block. The saturation assessment block is coupled to the signal input and configured to generate a scale increase request signal upon detection of a saturation condition. The full scale change block is coupled to the saturation assessment block and configured to generate a full scale change signal upon reception of the scale increase request signal.

  • Patent number: 10648813
    Abstract: A demodulator demodulates an in-phase component of an input signal which is in-phase and quadrature modulated. The demodulator includes a register storing a phase calibration value having an integer part and a fractional part. A noise-shaping modulator generates a succession of quantized values of integer type, the quantized values having a mean equal to the phase calibration value. A generating stage generates a demodulating signal phase locked with the input signal, the demodulating signal having a phase which depends linearly on the quantized values. A demodulating stage demodulates the input signal by means of the demodulating signal.
