発明の名称 (英語) Current amplifying element and current amplification method
発明の概要(英語) (US7902919)
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.
特許請求の範囲(英語) [claim1]
1. A current amplifying element comprising: an input current path which is formed between two input terminals and through which an input current flows;
an output current path which is formed between two output terminals and through which an output current flows, the output current path being approximately perpendicular to the input current path; and
a magnetic generator that generates a magnetic field that is approximately perpendicular to both the input current path and the output current path,
wherein the interaction between a current flowing through the input current path and the magnetic field generates a Hall electric field that amplifies an output current flowing through the output current path, and
wherein an insulator is interposed between the input current path and the output current path.
[claim2]
2. The current amplifying element of claim 1, wherein a distance between the two input terminals is longer than a distance between the two output terminals.
[claim3]
3. A current amplification method comprising: applying an input voltage across an input current path to cause an input current to flow along a first direction;
applying a magnetic field in a direction approximately perpendicular to the direction in which the input current flows;
wherein the interaction between current flowing through the input current path and the magnetic field generates a Hall electric field that amplifies an output current flowing through an output current path in a direction approximately perpendicular to the direction of the flow of the input current and the direction of the application of the magnetic field,
wherein an area where the output current flows is separated from an area where the input current flows by an insulator.
