Depending on the earthing configuration of the network, the instrument also uses multiphase measurements to calculate the impedance of the neutral conductor, enabling it to reveal defects that could ...

Some operational amplifiers (op amps) have an inductive open-loop output impedance, which can be more complex to stabilize than op amps with resistive output impedances. One of the most common ...

Keywords: Earthquake engineering, model-in-the-loop simulation, shake-table control, impedance matching, control-structure interaction, real-time feedback Seismic isolation Abstract: Model-in-the-loop ...

Many articles and application notes describe the extraction of phase margin, using a non-invasive technique that extracts the phase margin from an output impedance measurement. The term non-invasive ...

The Current Feedback Amplifier (CFA) burst onto the scene in the mid-1980s with the commercialization of this new topology by Comlinear Corporation. It quickly propagated industrywide with many ...
