Low-level current signal generator

Abstract

Signal generator circuits including a microcontroller for receiving a command signal, a function generator for outputting a waveform output, and a current stimulator circuit comprising a current divider portion and a current regulator portion, wherein the current divider portion is coupled to the function generator and receives the waveform output, and wherein the current regulator portion includes an output current, and further methods for applying a current having a targeted waveform to a load including the steps of providing a load having an impedance, providing a signal generator circuit coupled to the load, and commanding the signal generator to supply the targeted waveform to the load via the command signal to thereby apply the current having the targeted waveform to the load, wherein the command signal includes the parameters of the targeted waveform.
