    摘要: The invention is directed to a circuit for conditioning the output signal of a measuring sensor for further processing in a control apparatus which has a fixed ground potential which does not necessarily correspond to the ground potential of the measuring sensor. A conditioning circuit is provided which can be integrated on a chip and has the following characteristics. The conditioning circuit compensates for the fluctuating ground offset between exhaust gas probe and control apparatus ground when utilizing an exhaust gas probe burdened with a potential. The circuit arrangement includes an external circuit which can be changed to influence the input signal to the conditioning circuit. With this changeable external circuit, the output signal of the circuit arrangement can be so modified that the control apparatus outputs an output voltage with offset and an output voltage without offset. In the case of the external circuit for an output voltage without offset, an offset is impressed upon the input voltage which is then again subtracted at the output with an amplification factor so that the absolute value of the impressed offset has no influence on the output voltage.

    摘要: A p-channel transistor has a drain electrode (12), a source electrode (13), a gate electrode (16) and a bulk electrode (14), the drain and source electrodes (12, 13) being constructed as p-regions in an n-well (10) and the well (10) itself being embedded in a surrounding p-region.The bulk electrode is simultaneously the well terminal and is connected to the source electrode (13), while the drain electrode (12) is connected to the positive pole (U.sup.+) of the operating voltage. This arrangement confers a reliable resistance to polarity reversal in conjunction with a minimum area requirement; even at relatively high temperatures, only negligible leakage currents flow; and, there is a need only for a single well (10) on which it is also possible to accommodate still other components.

    摘要: A current mirror having at least one pnp-transistor and providing overvoltage protection has three collectors designed as partial collectors. Two of the partial collectors and the base are linked to a reference-current source and the other partial collector is linked to a terminal connection of the current source to be protected from overvoltage. In the event of an overvoltage across the terminal connection, an emitter is formed by the partial collector linked to this terminal connection which limits the received current in proportion, conditional upon the topology, with the mirror-reference current.
