| 摘要 |
The invention relates to an adaptive comparator circuit comprising a comparator with a threshold value input which receives a threshold voltage and a signal input which receives a voltage signal. The threshold value input is connected to one pole by means of a switch and connected to the other pole of a first voltage source by means of a capacitor. The threshold value input is also connected to the signal input of the comparator by means of a diode or a second voltage source. The switch is controlled by the control signal of a signal transmitter. When the switch is in a closed position, the capacitor is charged with the voltage of the first voltage source. When the switch is in an open position, the capacitor is discharged in such a way that the threshold voltage of the signal voltage is corrected at a given time interval.
