BIOLOGICAL TISSUE STIMULATOR WITH TIME-SHARED LOGIC DRIVING OUTPUT TIMING AND HIGH VOLTAGE STEP-UP CIRCUIT

摘要

42282 CAN 9A A biological tissue stimulator (10) having a time-shared logic element (16) alternately supplying switching signals (40) to a step-up voltage circuit (20) powered from a low-voltage power source (26) and supplying a plurality of amplitude timing signals (58, 60) to an output circuit (18) utilizing the high-voltage output (22) from the step-up voltage circuit (20). A high-voltage storage device (44) is utilized to store the voltage generated in the step-up voltage circuit (20) until it can be utilized by the output circuit (18).
