  • Publication number: 20130241636
    Abstract: An apparatus includes a circuit and a field line. The circuit includes a magnetic tunnel junction including a storage layer and a sense layer. The field line is configured to generate a magnetic field based on an input signal, where the magnetic tunnel junction is configured such that a magnetization direction of the sense layer and a resistance of the magnetic tunnel junction vary based on the magnetic field. The circuit is configured to amplify the input signal to generate an output signal that varies in response to the resistance of the magnetic tunnel junction.

  • Patent number: 5034697
    Abstract: A magnetic amplifier switch is connected to a transmitter and antenna of a LF transmitting system. The transmitter is operable to produce a signal which is modulated to first and second frequencies, for example "mark" and "space" frequencies, at different times. The magnetic switch is connected with inductors which are also connected with the transmitter and antenna. Opening and closing of the magnetic amplifier switch changes the inductance of the antenna such that the antenna is automatically tuned to resonance at the one or the other of the modulated frequencies being transmitted at a given time.

  • Patent number: 4458160
    Abstract: A single Josephson junction device is arranged in a single branch which comprises an external source resistor connected in series with an output resistor and a Josephson junction device. An input node and an input resistor are in series and connected to the node between the output resistor and the Josephson junction device. Voltage signals applied to the input voltage node are amplified by connecting a high gain voltage output in parallel with the output resistor and providing sensing means for sensing the voltage output across the output resistor only when the Josephson junction device is switching from its low impedance state to its high impedance state.

  • Patent number: 4015148
    Abstract: In accordance with the Hall effect, a magnetic field applied perpendicular to the direction of current flow through a conductor causes an electric field perpendicular to both the direction of the current flow and the direction of the magnetic field established in the conductor. This effect has been used to produce magnetic field and current detectors, modulators and frequency doublers. In accordance with the present disclosure a portion of the magnetic field is reversed to produce squaring of or obtaining the square root of the amplitude of the voltage used to produce the conductor current.
