ABSTRACT:
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.
