How Zener Diodes Work: Characteristics and Selection Guide
16 July 2026
Zener diodes are diodes that act as regulators. By using the reverse breakdown state of the PN junction, the current of the Zener diodes can be changed within a wide range while the voltage is unchanged.
An Overview of Top Semiconductor Companies
17 October 2025
The widespread use of semiconductors has changed our way of life. With the proliferation of electronic equipment, companies manufacturing semiconductors are booming.
What is SERDES?
04 November 2021
The abbreviation SERDES stands for SERializer/DESerializer in English. It's a point-to-point (P2P) serial communication technique that uses time division multiplexing (TDM). That is, at the transmitting end, multiple low-speed parallel signals are changed into high-speed serial signals, which are then re-converted into low-speed parallel signals at the receiving end via the transmission medium (optical cable or copper wire).
Introduction to STM32 Microcontrollers
12 March 2021
The STM32 series is based on the ARM Cortex-M3 core specially designed for embedded applications that require high performance, low cost, and low power consumption. This article introduces the definition, types, difference between the STM32 microcontroller and 51 microcontrollers as well as the basic system of STM32.
Thermistor: Characteristics, Classification, Symbol and Applications
10 December 2025
Thermistors are a class of sensitive components. They are divided into positive temperature coefficient thermistors (PTC) and negative temperature coefficient thermistors (NTC) according to different temperature coefficients.
Introduction to buck, boost, and buck-boost converters
28 September 2021
A buck converter (buck converter) is a DC-to-DC power converter that lowers the voltage from the source to the load (in drawing a smaller average current).A boost converter or a DC boost chopper is another name for a DC boost converter. A buck-boost converter is a DC-DC converter with an output voltage that can be higher or lower than the input voltage. This article mainly introduces these three converters and their working principles.
How to read Resistors Color Code?
16 October 2025
We can read the resistance value according to the resistors color code because of the use of four color bands or five color bands or six color bands on the resistors to indicate the resistance value. The color information representing the resistance value can be read at once from any angle.
Switching Power Supply Debugging: 10 Most Common Problems
26 December 2025
Hello everyone, I am Rose. Today I will introduce 10 common problems about SMPS debugging to you. Switch Mode Power Supply (SMPS for short), also known as switching power supply, switching converter, is a high-frequency power conversion device and a type of power supply.
Voltage Regulator: Types, Working, and Applications
23 February 2021
A voltage regulator is a part of the power supply device that, under all operating conditions, ensures a stable, continuous voltage supply. During power changes and differences in loads, it controls voltage. As well as DC voltages, it will control AC. We will take a closer look at the idea of a voltage regulator and the different forms in this blog, and we will expand on the common voltage regulator ICs and their common implementations!
MOSFET vs IGBT: Structure, Switching Behavior, and How to Choose
14 July 2026
With the rise of new energy in recent years, the market demand for MOSFETs and IGBTs is increasing steeply. Generally used as switching devices, they are widely used in electronic circuits. MOSFETs and IGBTs are relatively similar in appearance and characteristics parameters. So what is the difference between MOSFETs and IGBTs?
What is a Decoder?
15 June 2026
A decoder is a type of circuit that can translate the state of the input binary code into an output signal to express its original meaning. It can be said that the circuit that realizes the specific meaning of the code state is called a decoder.
