Abstract: A Hall sensor compensation circuit includes an input node configured for receiving a bias signal for a Hall sensor. A bias node provides to the Hall sensor a compensated bias signal. A compensation network coupled between the input node and the bias node has a gain inversely proportional to Hall mobility, μn′, wherein the Hall sensing signal is temperature-compensated.

Abstract: Hall sensing signals are received in a spinning readout pattern of subsequent readout phases, wherein the pattern is cyclically repeated at a spinning frequency and a polarity of the Hall sensor signals is reversed in two non-adjacent readout phases of the readout pattern. A signal storage circuit includes signal storage capacitors. An accumulation circuit includes accumulation capacitors. A switch network is selectively actuated to couple the signal storage capacitors with the accumulation capacitors synchronously with phases in the spinning readout pattern in subsequent alternating first and second periods. The spinning output is stored with alternating opposite signs on the signal storage capacitors and the Hall sensing signals are stored in the signal storage capacitors and then accumulated on the accumulation capacitors with alternate signs in subsequent periods. The accumulated output signal is then demodulated with a demodulation frequency half the spinning frequency.

Abstract: An integrated sensor device including a first die, housing a sensor element to detect a quantity external to the sensor device and transduce the external quantity into an electrical sensing signal; a second die mechanically coupled to the first die so that the first and second dies are stacked on one another along one and the same axis; and at least one heater of a resistive type integrated in the first die and/or in the second die, having a first conduction terminal and a second conduction terminal configured to couple respective first and second conduction terminals of a signal generator for causing an electric current to flow, in use, between the first and second conduction terminals of the heater and generate heat by the Joule effect. It is possible to carry out calibration in temperature of the sensor element.
