Abstract :
A new gyrator using switched mode operations and its applications to very low-frequency signal measurements are described. The proposed method is particularly effective for obtaining equivalent inductances with large values (¿ 107 H). Thus variable filters and tuning devices in very low frequency regions can be constructed with the new gyrator. The basic arrangement, principles, characteristics, and applications of the switching mode gyrator are presented. Experimental results measured for ultralow frequency electrical signals are also shown.
