    Abstract: A magnetic sensor is formed by a fluxgate sensor and by at least one Hall sensor integrated in a same integrated device, wherein the magnetic core of the fluxgate sensor is formed by a magnetic region that operates also as a concentrator for the Hall sensor. The magnetic region is manufactured in a post-machining stage on the metallization layers wherein the energizing coil and sensing coil of the fluxgate sensor are formed; the energizing and sensing coils are formed on a semiconductor substrate housing the conductive regions of the Hall sensor.

    IPC: G01N27/409 ,  H03F3/45

    Abstract: In order to achieve a high input dynamic range as well as high CMRR and PSRR values and input impedance with the use of a single supply voltage (Vcc), the amplifier includes an input stage with two transistors (Q1, Q2) which are biased by a constant current (IP3, IP4), preferably of less than 1 microampere, and the collectors of the transistors (Q1, Q2) are kept at fixed reference voltages (VR1, VR2). The input signal (VIN) applied between the emitters (IN(-), IN(+)) of the transistors (Q1, Q2) is transferred to the terminals of a first resistor (R1) which is supplied with current (IR1) from a circuit (M7, A5, R3; M10, Q6, R4; M9, Q7, R5) which mirrors the current (IR1) into a second resistor (R6), from the terminals of which the output signal (VOUT) is taken. The preferred application is for forming interfaces for lambda probes fitted to catalytic converters for motor vehicles.

    Abstract: The circuit includes two output terminals (OUT1, OUT2) for connection to the terminals of a load (L), first and second pairs of electronic power switches (Q1, Q4; Q2, Q3) which are connected between the output terminals (OUT1, OUT2) and the two poles of a direct-current voltage supply (Vs) so as to form an H-shaped structure with the load (L), and a driver circuit (C1, C2) for selectively making the electronic power switches of the first pair (Q1, Q4) of the second pair (Q2, Q3) order to cause a current to flow through the load (L) in one direction or the other respectively, and for preventing the electronic switches (Q1, Q3; Q2, Q4) which are connected between the same output terminal (OUT1; OUT2) and the two poles of the voltage supply (Vs) from conducting simultaneously.
