ABSTRACT:
An electrical stimulator for biological tissue utilizing a linear current output circuit. A digital-to-analog circuit converts a digital output word to an analog value and feeds a current amplifier having negative feedback. The output current of the amplifier is transformer driven through a push-pull transistor network. A reference impedance provides a voltage indicative of the current output which is fed back to an operational amplifier.
