What is a magnetic sensitive transistor, its structure, characteristics, principles, applications, discrimination, and operating procedures 1

A magneto sensitive transistor is a semiconductor device that can change its resistance value in a magnetic field. It is a new type of AD73311ARSZ magnetic sensing device developed on the basis of transistors, which has the characteristics of high sensitivity, low drift, and high stability.

1、 Structure:

The structure of a magnetic sensitive transistor mainly consists of a source, a drain, a gate, and a magnetic sensitive layer. Among them, the source and drain are connected through a magnetic sensitive layer, while the gate is isolated from the magnetic sensitive layer through an insulating layer. The resistance value of the magnetic sensitive layer will change with the external magnetic field, thus achieving sensitive detection of the magnetic field.

2、 Characteristics:

1. Highly sensitive: Magnetic sensitive transistors have a high sensitivity to magnetic fields and can quickly and accurately detect changes in magnetic fields. transistor

2. Fast response speed: Due to the characteristics of magnetic semiconductor materials, magnetic sensitive transistors have a fast response speed.

3. Simple structure: Due to its simple basic structure, it is easy to produce and integrate into the system.

3、 Principle:

The working principle of a magnetic sensitive transistor is mainly achieved by utilizing the change in resistance value of semiconductor materials in a magnetic field. When the magnetic field changes, the resistance value of the magnetic sensitive layer also changes, thereby altering the conduction state of the transistor. This change can be detected by the circuit, thereby achieving the detection of the magnetic field. transistor
