Abstract
Generally, in accordance with the various illustrative embodiments disclosed herein, a current sensing probe includes a current-to-voltage conversion circuit that not only presents a desirable impedance into an inductive current sensing element of the current sensing probe, but also remains operationally stable over a wide range of frequencies when measuring a current flowing through a device-under-test. The wide frequency range can extend down to some low frequencies that can prove challenging to conventional current sensing probe circuits.
