    Abstract: PURPOSE: To provide a relatively easily realizable circuit capable of generating the reference voltage of the relatively low value of the order of several tens mV without heat drift. CONSTITUTION: A difference between the base-emitter joining voltages of two different transistors Q6 and Q7 and the preset fraction of the base-emitter joining voltage are totalized. The circuit for performing the function is provided with a first circuit capable of generating a first voltage V1 equal to the fraction of a base-emitter voltage, an operational amplifier capable of generating a total voltage in an output node and a means for controlling a bias current through an input transistor pair.

    Abstract: In a pressure sensor (35), a pressure-sensor element (10) has a monolithic body (12) of semiconductor material, and a first main face (12a) and a second main face (12b) acting on which is a stress resulting from a pressure (P) the value of which is to be determined; and a package (36) encloses the pressure-sensor element (10). The package (36) has an inner chamber (37) containing liquid material (38), and the pressure-sensor element (10) is arranged within the inner chamber (37) in such a manner that the first and second main faces (12a, 12b) are both in contact with the liquid material (38). In particular, the liquid material is a silicone gel.
