    Abstract: An all-digital phase locked loop (ADPLL) generates a feedback word representing a continuous-time oscillating signal. The ADPLL includes a time-to-digital converter (TDC) configured to be input with the continuous-time oscillating signal and a reference signal. The reference signal is a function of a reference clock signal. The TDC is configured to generate a digital word, the feedback word being a function of the digital word. The ADPLL includes a delay circuit configured to be input with at least one of the reference clock signal and the continuous-time oscillating signal and to be controlled by a first dither signal.

The circuit includes a diode-connected transistor biased with a first constant current in a saturation functioning condition, a sense transistor mirrored to the diode-connected transistor and biased in a linear (triode) functioning condition, a load transistor connected in series to the sense transistor, biased with a second constant current and the control terminal of which is connected in common with the respective terminals of the diode-connected transistor and of the sense transistor. The input current to be compared is injected to a common current node of the load transistor and of the sense transistor, and the output voltage is available on the other current node of the load transistor.

    Abstract: Measurements are acquired from a magnetic sensor during a non-pre-ordered movement, and a plurality of sets of solutions are determined for respective expected values of intensity of the Earth's magnetic field. The solutions are defined by a plurality of parameters, including at least one gain value for each detection axis of the magnetic sensor. For each solution, a figure of merit is determined, correlated to a calibration error, and a partial solution is selected in each set of solutions, based on the figure of merit. Once a gain confidence interval has been defined, a calibration solution is selected based on the figure of merit, from among the partial solutions having respective gain values all falling within the gain confidence interval.

    Abstract: The method of synchronizing sequential phase switchings in driving stator windings of a multiphase sensorless brushless motor with a reconstructed information on the current angular position of a permanent magnet rotor, includes sampling on a currently non-conductive stator winding a voltage induced thereon by the resultant magnetic field produced by the drive current forced through currently conductive stator windings that inverts its sign when the rotor transitions across a plurality of significant angular positions, at which orthogonality between the resultant magnetic field and a magnetic axis of the non-excited winding verifies. The sign of the sampled voltage induced on the currently non-excited winding is compared with the sign that is expected upon transiting across the angular position of inversion by the moving rotor for the current phase drive configuration to sequentially switch to the next phase drive configuration upon verifying conformity of the sign of the sampled voltage with the expected sign.
