Abstract
Impedance measurements based on voltage pulse injection and current detection are faster and easier to implement than measurements based on sine waves, but transients produced in the current-to-voltage
conversion may lead to large deviations in the measurement result. Because those transients depend on the same
impedance being measured, solutions based on specific circuit values fail for large measurement ranges. We
propose to reduce those transients by controlling the rise time of the pulse being applied to the impedance under
test. For a particular implementation of the method, transient amplitude has been reduced to less than 1 % of the full scale voltage, as compared to 40 % overshoot when faster voltage pulses were applied.
