Switching Diodes Basics: Working, Types and Circuit Analysis
24 October 2025
Switching Diodes are a type of semiconductor diode. They are specially designed and manufactured for "on" and "off" on a circuit. As the name suggests, it refers to a diode with a switching function.
Inductor Basics: Structure, Parameters, and Measurement
24 October 2025
Inductors are components that can convert electrical energy into magnetic energy and store it. An inductor generally consists of a skeleton, a winding, a magnetic core, an iron core, a shielding case, and a package. Commonly used inductors are adjustable inductors and choke inductors. In the circuit, the inductor prevents the AC and allows DC to pass through.
Introduction to Types of Motion Sensors
24 October 2025
Motion sensor refers to a device that detects the motion of an object or person, including gravity, linear acceleration, rotation vector, vibration frequency, etc. Motion sensors can be used to monitor device movements such as tilt, shake, rotation, or swing. Among them, the rotation vector sensor and the gravity sensor are the most commonly used sensors for motion detection and monitoring. Today we come to learn about various types of motion sensors, including accelerometers, tilt sensors, vibration sensors, PIR (passive infrared) sensors, and rotation sensors.
Introduction to Temperature Sensors
24 October 2025
The temperature sensor refers to a sensor that can sense the temperature and convert it into a usable output signal, which is the core part of the temperature measuring instrument. It's divided into 5 types and each type has unique working principles. Besides, some factors need to be noticed in the installation and using process. For the temperature sensor can accurately measure the ambient temperature, it's widely used in various fields and provide convenience for people's production and daily lives.
What are Proximity Sensors?
24 October 2025
The proximity sensor is a general term for a sensor that replaces contact detection methods such as limit switches. It aims to detect without contacting the detection object. It can detect the movement information and presence information of the object into electrical signals.
An Overview of Linear Integrated Circuits
23 October 2025
A linear integrated circuit is an integrated circuit based on an amplifier. The meaning of "linear" used to indicate that the response relationship of the amplifier to the input signal is usually linear.In this essay, we’ll first introduce the development history of linear integrated circuit. And then the production process and the high-frequency technology are discussed in detail. The following two parts mainly talk about the linear integrated circuit types and forms. And the final chapter analyzes the two typical bipolar linear integrated circuit一 Lm386 and 34063.
Types, Structure, and Packages of Integrated Circuits
23 October 2025
The type of integrated circuit can be divided according to its use, function, structure, manufacturing process, integration, and conductivity type. The structure of the integrated circuit can be learned from levels from top to bottom: system level - module level - register transfer level (RTL) - gate level - transistor level. The packaging forms of integrated circuits include SOP, PGA, BGA, DIP.
What are the Differences Between Pull up and Pull down Resistors?
22 October 2025
Pull up is to clamp an uncertain signal to a high level with a resistor, and the resistor also acts as a current limiter. In the same way, pull down means to clamp the uncertain signal to a low level through a resistor. To pull up is to input current to the device, and the pull-down is to output the current.
Analysis of Semiconductor Wafers
22 October 2025
The wafer is the basic raw material for manufacturing semiconductor devices. Various circuit element structures can be fabricated on silicon wafers, thereby becoming integrated circuit products with specific electrical functions.
Diodes Tutorial: How to Test Diodes?
22 October 2025
A diode is an electronic device made of semiconductor materials. The diode is one of the earliest semiconductor devices, and it is widely used, especially in various electronic circuits.
Introduction to Photonic Integrated Circuits and PIC Technology
22 October 2025
The concept of the photonic integrated circuit is similar to the concept of electronic integrated circuits. However, electronic integrated circuits integrate transistors, capacitors, resistors, and other electronic devices, while PIC integrates various optical devices or optoelectronic devices, such as lasers, electro-optical modulators, photodetectors, optical attenuators, optical multiplexers/demultiplexers, and optical amplifiers.
What is a Semiconductor?
22 October 2025
Semiconductor refers to a material whose conductivity is between a conductor and an insulator at room temperature. Semiconductors are used in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting applications, and high-power power conversion.
