Abstract:

A multichannel stimulator device has a host user interface circuit for enabling a user to select a channel and easily create and display a stimulus wave signal for the selected channel and generate a data signal specifiying the channel and stimulus wave signal. The stimulator also includes a master circuit for receiving the data signal and directing it to the specified channel as a wave building instruction signal. A slave circuit associated with the channel specified receives the wave building signal and responds by generating a corresponding low power stimulus wave signal in the channel specified. Then an output circuit coupled to the slave circuit electrically isolates the low power stimulus wave signal from other channels, amplifying and converting it to a corresponding high fidelity current stimulus wave signal.
