Abstract
An electrical signal supply apparatus independently controls and regulates voltage and current in supplying microampere currents to skin tissue of patients. The apparatus enables operators to select a desired voltage level independent of the requirement to maintain current through the skin tissue at a relatively constant level. The apparatus includes a switching regulator in combination with an electric voltage doubling network and potential divider network to enable the supply of increased voltages.
