To damp transients that are generated by a complex load on its input terminals that are connected to a first supply voltage, one input terminal (IN2) is connected to an output terminal of a buffer amplifier (1), to the (+)-input terminal of a differential amplifier (2) via a first resistor (R1), and to the (-)-input terminal of the differential amplifier (2) via a first capacitor (C1). The other input terminal (IN1) is connected to the (+)-input terminal of the differential amplifier (2) via a second resistor (R2) that is connected in parallel with a second capacitor (C2). The output terminal of the differential amplifier (2) is connected to the input terminal of the buffer amplifier (1) via a third capacitor (C3), and to the (-)-input terminal of the differential amplifier (2) via a third resistor (R3). The buffer amplifier (1) and the differential amplifier (2) are connected with one supply voltage terminal to said other input terminal (IN1) and with the other supply voltage terminal to a further input terminal (IN3) that is connected to a potential that is higher than the potential that is connected to said one input terminal (IN2). |
