    Abstract: An electrical channel having inbuilt current limiting is provided. The electrical channel includes an electrode current source. The electrode current source includes a voltage-to-current converter, a negative impedance converter, and at least one passive current limiting component. Further, the voltage-to-current converter is configured to receive an input voltage and output a corresponding output current. Moreover, the negative impedance converter is operatively coupled to the voltage-to-current converter, where the negative impedance converter is configured to cancel an output impedance of the voltage-to-current converter, a parasitic impedance, or both. Also, the passive current limiting component is configured to limit the output current to a load below a threshold value.
