In a sampling circuit including a first main terminal (P) and a series coupling of a hold capacitor (C2) and a sampling switch (S2) between the first main terminal (P) and a second main terminal (E), a parallel circuit (L2, R4) of a coil and a resistor (L2) is coupled in series with the sampling switch (S2) and the hold capacitor (C2), whereby the combination of the coil (L2), the resistor (R4) and the hold capacitor (C2) generate an excitation within a time period in which the sampling switch (S2) is conductive. |
