Several circuit designs and hardware implementations of probe current sources for broadband electrical impedance measurements were compared. The basic parameters of the circuits were studied by numerical methods. Various hardware implementations were experimentally tested. Printed circuit board topologies providing parameters close to those obtained by model estimation were suggested.
