摘要： A voltage regulator contains a reference which provides a value for comparison by an error amplifier which generates a control signal in response to the deviation of the output to the reference. As many stages of the circuit as possible are connected to fixed potential points. The fixed potential points are fixed with respect to the regulated output voltage. This provides a voltage regulator which is insensitive to interference signals from the unregulated supply voltage. The interference signals from the supply voltage are further buffered by using relatively small capacitors within the circuit, rather than a large external filter means.

摘要： In this protective arrangement, a resistor between a pad (p) and a transistor to be protected is implemented with an expansion region (e) which lies completely below the pad (p) and extends beyond the latter along the entire circumference of the pad. An elongate region (z) extends along the circumference of the expansion region (e) and is connected to circuit ground via an interconnection track (b). The connection between the elongate region (z) and the interconnection track (b) has a low resistance.

摘要： To detect a fault state due to a line break in power supply lines on the receiving side during the operation of a transducer device, the transducer output voltage is forced to an extreme voltage range by a co-integrated p-channel-depletion-transistor. As a result, the signal detection device can reliably detect the presence of the fault state due to a line break in the supply feed lines.

摘要： The present invention is a monolithic integrated differential amplifier having an operational amplifier and a digitally controlled means for setting the gain of said differential amplifier wherein the gain is adjustable by means of a resistive feedback network formed by a resistor chain whose taps are coupled via a multiplexer to the operational amplifier. The operational amplifier in the present invention is designated as an adaptive amplifier because its gain-bandwidth product is digitally adjustable in steps, with the respective gain-bandwidth product selected being adapted to the gain setting of the monolithic integrated differential amplifier.
