1. A method for adjusting a compliance voltage in a stimulator device, the device comprising at least one source circuit coupled to the compliance voltage, at least one sink circuit coupled to a reference voltage, and at least two electrodes, the method comprising:

  • providing at least one stimulation pulse to a load between the at least two electrodes, wherein at least one electrode is coupled to a source circuit and wherein at least one electrode is coupled to a sink circuit;

    during the at least one stimulation pulse, measuring an output voltage across the source circuit and measuring an output voltage across the sink circuit; and

    using the measured output voltages across the source circuit and the sink circuit to adjust the compliance voltage in an attempt to bring at least one of the output voltages to a suitable level.
