Abstract
An electrical current measurement system. A sense impedance and a composite amplifier are in electrical communication and together define a trans-impedance circuit that presents a frequency-compensated impedance lower than the sense impedance to an input electrical current to be measured. A sense amplifier in electrical communication with the sense impedance provides an output indicative of a magnitude of the input electrical current. A current bypass circuit may parallel the trans-impedance circuit and bypass the input electrical current around the trans-impedance circuit when the current reaches a predefined magnitude. The system may be combined with another current sensor to form a dual-range current measurement instrument.
