Abstract

The present invention relates to a stimulator device, comprising a plurality of electrode nodes, wherein each of the electrode nodes is associated with a different electrode configured to contact a patient's tissue, a DC-blocking capacitor between each of the electrode nodes and its associated electrode, wherein at least one of the electrodes comprises a sensing electrode to receive a voltage from the tissue, wherein each electrode node associated with the at least one sensing electrode comprises a sensing electrode node, sense amplifier circuitry comprising a first input connected to one of the at least one sensing electrodes and a second input, the sense amplifier circuitry further comprising a differential output comprising a first output and a second output, and DC offset compensation circuitry configured to receive the first and second output, and to produce a DC current, wherein a magnitude of the DC current is a function of a difference of voltages at the first and second outputs, wherein the DC current is provided to the first input to adjust a DC voltage at the first input equal to a DC voltage at the second input.
