Abstract: A device for reducing the electromagnetic emission in integrated circuits having driver stages reduces the electromagnetic emission of an integrated circuit without requiring an increase in the blocking capacitance in the process. This is achieved by combining driver stages which do not switch simultaneously to form driver groups, and special wiring of a plurality of blocking capacitors.

Abstract: The invention relates to an arrangement (10) and a method for adjusting the slope times of one or more drivers (90) in such a way that the adjustment is essentially independent of external conditions. The invention also relates to a driver circuit. The arrangement (10) is provided with a device (20) for detecting the time history of an output voltage that is output and supplied to a load (12) by means of the driver/s (90). The measured time values are converted into an output voltage value in a device (36) for converting the measured time history of the output voltage. Moreover, a device (40) for generating a reference voltage value is provided. The device (40) is connected to a device (60) for predetermining a desired slope time for the driver/s (90), whereby the slope time is essentially independent of external conditions. A system pulse can be partitioned into differently long rectangular pulses in the device (60) in such a way that the user of the arrangement (10) can select from the group of the rectangular pulses which match certain slope times respectively. The output voltage value and the reference voltage value are compared in a comparing device (50) that is also connected to the driver/s (90) in such a way that the driver/s (90) can be readjusted thereby.

Abstract: The bus driver (1) has a compensation device (8,9,15), which alters the signal fed to the driven bus line (3), for compensating the interference from at least one signal carried by an adjacent bus line (6,7) which is capacitively coupled to the first bus line. The bus drive has an inverter circuit (2), with the compensation device incorporating a second parallel inverter (8,9), for each of the bus lines capacitively coupled to the driven bus line.
