摘要： Disclosed are systems and methods which provide voltage conversion in increments less than integer multiples of a power supply (e.g., battery) voltage. A representative embodiment provides power supply voltage multipliers in a binary ladder distribution to provide a desired number of output voltage steps using a relatively uncomplicated circuit design. By using different sources in various combinations and/or by “stacking” different sources in various ways, the voltage multiplier circuit may be used to provide desired voltages. In order to minimize the number of components used in a voltage converter of an embodiment, a capacitive voltage converter circuit uses one or more storage capacitors in place of pump capacitors in a voltage generation cycle. Also, certain embodiments do not operate to generate an output voltage until the time that voltage is needed.

摘要： To avoid charge accumulation on capacitive connections to implanted electrodes during delivery of stimulation pulses, stimulation pulses are followed by active discharge pulses having opposite polarity of the stimulation pulses. The active discharge pulses preferably have at least one pulse attribute magnitude (e.g., duration, voltage, and/or current) different than a corresponding stimulation pulse and are preferably programmable. Approximately the same total net current flow is delivered during active discharge pulses as during the stimulation pulses, but in the opposite direction and optionally at a lower amplitude. In addition, by reducing the driving voltage and a variable load within the electrical path for delivery of the pulses, power dissipation during active discharge is preferably reduced.

摘要： A low power (and lower cost) implementation for amplifier used in delivering a stimulation pulse is provided according to embodiments through use of a pre-charge period for each pulse. For example, a voltage at a variable output terminal of a digital-to-analog converter is increased on the leading edge of PULSE and INVERTCLK signals to result in an output of an operational amplifier increasing to a predetermined voltage prior to output of a stimulation pulse, according to an embodiment. A shunt path may be implemented to shunt current away from a load during the pre-charge period.
