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.

Abstract: An integrated circuit includes a control circuit, a primary sensor device coupled to the control circuit, and a plurality of groups of secondary sensor devices coupled to the primary sensor device. The primary sensor device receives a master clock signal from the control device and outputs, to each group of secondary sensor devices, a respective secondary clock signal with a frequency lower than the primary clock signal. The primary sensor device generates primary sensor data. The primary sensor device receives secondary sensor data from each group of secondary sensor devices. The primary sensor device combines the primary sensor data and all of the secondary sensor data into a sensor data stream with a time division-multiplexing scheme and outputs the sensor data stream to the control circuit.

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.

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.

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.
