Abstract

The integrated low-pass filter has a resistor connected, on the one hand, to an input terminal and, on the other hand, to a first capacitor and to the control terminal of a transistor. The output circuit of the transistor is connected, on the one hand, to the first capacitor and to an output terminal of the circuit. Furthermore, the output circuit of the transistor is also connected, via a current source and a second capacitor, to a first reference potential. On the other end, the output circuit of the transistor is connected to a second reference potential.
