Abstract
The invention is a method and circuit for improving the settability of the output current (i1) of at least one pad driver (D: D1, D2, . . . Dn) to reduce interfering voltage dips on the supply lines. The pulselike current peaks caused by rapid charging/discharging of high load capacitances (c) are particularly avoided. To this end, the respective output transistor (t1, t1') is operated as a current-controlled element in a first range (b1) of the output voltage (OUR) and as a voltage-controlled element in a second range (b2).
