Abstract
A free running oscillator clocks a counter, which produces stimulation control signals at a predetermined counter. An output stage includes transistors, energized by the counter, to issue stimulating pulses having a voltage equal to that across a capacitor in parallel with the output stage. The output capacitor is charged, between output pulses, by successive charge sharing cycles with at least one other capacitor, which is enabled by a stored program word, at a rate determined by the oscillator output cycles.
