Beschreibung
Zusammenfassung:	A leakage-current compensation circuit including: a first node for connection of a first component, a first leakage current flows through the first component and node with a given polarity, the magnitude of the first leakage current dependent on a first potential difference across the first component; a second component connected to a second node with a second leakage current flowing through the second component and node, the magnitude of the second leakage current dependent on a second potential difference across the second component; a current mirror connected to the first and second nodes to cause a compensation current, the magnitude of the compensation current dependent on the magnitude of the second leakage current; a differential amplifier connected in series with the second component along a current path carrying the second leakage current; and an AC coupling superimposing an AC-component of the first potential difference on the second potential difference.
