摘要：Disclosed herein are methods and circuitry for monitoring and adjusting a
compliance voltage in an implantable stimulator devices to an optimal value that issufficiently high to allow for proper circuit performance (i.e., sufficient current output),but low enough that power is not needlessly wasted via excessive voltage drops acrossthe current output circuitry. The algorithm measures output voltages across the currentsource and sink circuitry during at least periods of actual stimulation when both thecurrent sources and sinks are operable, and adjusts the compliance voltage so as toreduce these output voltages to within guard band values preferably indicative foroperation in transistor saturation. The output voltages can additionally be monitoredduring periods between stimulation pulses to improve the accuracy of the measurement,and is further beneficial in that such additional measurements are not perceptible to thepatient.
