A driver circuit for providing an output signal for switching an electrical load on and off has a field-effect transistor having a gate terminal and an output for providing the output signal to the electrical load, a buffer circuit connected to the gate terminal of the field-effect transistor to impress a charge change current on the gate terminal of the field-effect transistor based on a drive signal, and a comparator having a first input for receiving the gate voltage and a second input for receiving the output signal to determine whether the gate voltage and the output voltage fulfill a predetermined relationship with respect to each other, and to provide the drive signal to the buffer circuit so that the charge change current is changed in magnitude when the predetermined relationship is fulfilled as compared to the charge change current when the predetermined relationship is not fulfilled.

Driver circuit for providing an output signal

The invention relates a substrate for a package for an electronic circuit and methods for packaging an electronic circuit with a substrate. The substrate comprises at least one conduction region and an activation region arranged within the substrate. The activation region is generally in contact with the conduction region and is configured to change its electrical resistance when activation occurs.

The present invention relates to an input circuit for receiving an input signal in an integrated circuit, having a differential amplifier whose first input can have a predetermined reference voltage applied to it and whose second input can have the input signal applied to it, and having a current source for operating the differential amplifier at its operating point, wherein a setting circuit is connected to the current source in order to set the operating point of the differential amplifier in an optimum manner on the basis of the predetermined reference voltage.

Input circuit for receiving an input signal, and a method for adjusting an operating point of an input circuit

One embodiment of the invention provides an output driver for an integrated circuit. The output driver has a driver circuit for driving an input signal onto an output line. The driver circuit is dimensioned in such a way as to supply a current intensity dependent on the input signal to be driven and/or a potential dependent on the input signal to be driven on the output line. The current value and/or the potential value lie in a current intensity range and/or potential range defined by a predetermined specification. The driver strength of the driver circuit may be set in accordance with a control signal. A measuring circuit is provided to measure the current intensity of the current flowing on the output line and/or the potential of the output line. A control circuit serves for setting the driver strength of the driver circuit so that the potential on the output line is set to a potential value and/or the current intensity is set to a current value, wherein the set potential value and the set current value may lie in a lower power range of the current intensity range and/or potential range prescribed by the specification.
