Characterization of the Magnetic Second-Harmonic Analog Memory

Abstract—The magnetic second-harmonic analog memory is a device capable of performing the functions of an integrator and an analog memory. The device consists of two magnetic cores wound in such a way that an output voltage of even-harmonic relationship to a drive voltage is produced having an amplitude proportional to remanent core flux. In the following paper, device performance and fundamental design criteria are discussed. Although electrical characterization is emphasized, device performance in a hostile thermal and mechanical environment is also considered briefly.
