Beschreibung
Zusammenfassung:	An electrical stimulation and monitoring device comprises several signal paths which are connected in parallel with each other, and each containing a stimulation or sensing electrode (25, 35), a DC-blocking capacitor and a stimulation or sensing channel (26, 36). A semiconductor substrate (100) used for hosting the DC-blocking capacitors is connected electrically to a DC voltage source (2) through a substrate holding capacitor. Such substrate holding capacitor reduces a blanking time between stimulation and sensing periods, and also reduces cross-couplings between different ones of the signal paths while all the DC-blocking capacitors are provided on one and same semiconductor substrate.
