Abstract:
A method for reducing a disturbance on a signal path is provided. The disturbance is caused by a capacitance (203, 214)of a semiconductor switch (131-133) of an integrated circuit (130). The semiconductor switch (131-133) switches the signal path. The capacitance (203, 214) acts between the semiconductor switch (131-133) and a power supply terminal of the integrated circuit (130). According to the method, the power supply terminal of the integrated circuit (130) is coupled via an impedance (138, 139) to a power supply (137, 140).
