Abstract :
Circuit-based, small-signal models of the magamp which include the effects of the nonideal squareness of the magamp´s core B-H curve are derived for both the voltage-reset and current-reset control techniques. Since in this modeling approach, the small-signal behavior of the magamp is described by equivalent circuits, circuit simulators can be easily used to facilitate the control-loop design optimization of the magamp.
