Voltage/current regulator improvements for an implantable medical device

A method for generating a neurological stimulation waveform with an implantable medical device, the steps comprising the steps of:

• (a) configuring a capacitor arrangement with respect to an electrical reference, wherein the capacitor arrangement comprises a plurality of capacitors;
• (b) connecting a first regulator to the capacitor arrangement in order to obtain a first value of voltage;
• and
• (c) reconfiguring the capacitor arrangement with respect to the electrical reference in order to obtain a second value of voltage, the second value of voltage associated with the first regulator.
