High-current-gain current mirrors
Real current operating amplifiers are based on high-current-gain, going to infinity in ideal case. This high current gain is usually solved in the internal structure by flowing mirrored input current into the high-...

Measurement of DC Currents in the Power Grid by Current Transformer
DC currents in power grids are mainly caused by geomagnetic activity especially during magnetic storms. It is desirable to monitor these currents to prevent saturation of transformers, which may cause blackout. However, adding DC
