Abstract: A magnetic field sensor arrangement (4) comprises a stacked arrangement (1) with a first magnetic field sensor body (20) and a second magnetic field sensor body (40). The first magnetic field sensor body (20) has a first main surface (21), on which is arranged a first magnetic field sensitive element (23), and a second main surface (22), which is approximately parallel to the first main surface (21). The second magnetic field sensor body (40) has similarly a first main surface (41), on which is arranged a second magnetic field sensitive element (43), and a second main surface (42), which is approximately parallel to the first main surface (41).

Abstract: A voltage generator arrangement which comprises a voltage converter (40) and a polarity detection circuit (10). The voltage converter (40) is coupled to a supply voltage terminal (9) and an output terminal (7) and comprises a first mode of operation (P1) for a positive supply voltage (VIN) and a second mode of operation (P2) for a negative supply voltage (VIN). The polarity detection circuit (10) is coupled to the supply voltage terminal (9) and a control input terminal (47) of the voltage converter (40), for providing a first pilot signal (SP1) depending on the polarity of the supply voltage (VIN).
