摘要: A signal amplifying system having an oscillator and an amplifying circuit. The oscillator has a first resistor with a first resistance R1 and a first capacitor with a first capacitance C1, and generates an oscillating signal having a frequency f which equals to k1/(R1*C1), k1 is a first proportional parameter. The amplifying circuit has an input terminal to receive an input signal and amplifies the input signal under the control of the oscillating signal. The amplifying circuit has a second resistor with a second resistance R2 and a second capacitor with a second capacitance C2. The amplifying circuit has a −3 dB bandwidth W−3 dB which equals to k2/(R2*C2), k2 is a second proportional parameter. In this signal amplifying system, the product of the first resistance R1 and the first capacitance C1 is proportional to the product of the second resistance R2 and the second capacitance C2.

摘要: A high temperature magnetic amplifier, which utilizes the nonlinear properties of square loop magnetic cores to achieve very large amounts of both voltage and power amplification. By combining square loop, grain-oriented magnetic materials with high temperatures along with high temperature packaging approaches, high temperature long lifetime components can be produced. The high temperature magnetic amplifier is used as a building block to develop high temperature versions of operational amplifiers, comparators, voltage regulators, timers, counters, modulators, motor starters, servo systems, converters, inverters, power switches and many other devices.

摘要: 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.

摘要: A current amplifying element that operates at a higher speed than conventional semiconductor devices is provided. An input current flows through an input current path 60 in a direction X, and a magnetic field generated from a magnet 90 is applied in a direction Z which is perpendicular to the direction X. An output current path 70 is formed under the input current path 60 with an insulator 80 interposed therebetween. Since the direction in which an output current flows is perpendicular to both the input current and the magnetic field, the current is amplified by the galvanomagnetic effects produced by the input current and the magnetic field.
