DIGITAL CIRCUIT FOR CONTROL OF GRADUAL TURN ON OF ELECTRICAL TISSUE STIMULATORS |
摘要 |
<p>A circuit for causing the gradual turn-on of electrical tissue stimulation in a digitally controlled stimulator is disclosed. A stimulation pulse counter and a pulses per step memory circuit are connected to a decoder to provide an amplitude incrementing signal after a presettable count of stimulation pulses. An amplitude counter receives the incrementing signal to increment the amplitude of the stimulation output pulse through a digital to analog converter circuit and to reset the pulse counter. A maximum amplitude memory circuit and decoder operate in conjunction with the amplitude counter to latch the counter when a preset pulse amplitude is obtained. At the end of a stimulation interval, the amplitude counter is reset and stimulation pulses begin at the minimum amplitude at the start of the next stimulation interval.</p> |
