Abstract: The disclosure describes tissue resistance measurement techniques. To avoid errors caused by bandwidth limitations of the amplifier that amplifies a signal used to determine the tissue resistance, the disclosure describes determining values at different frequencies, where the values include respective error values. The respective error values are proportional to the respective frequencies, and based on this relationship the error value can be removed from the tissue resistance measurement.
