The History of Thermometers09 January 2026
Hello everyone, I am Rose. Today I will introduce you thermometers. Thermometers are tools that can accurately judge and measure temperature and are divided into pointer thermometers and digital thermometers. According to the difference of the purpose of use, a variety of thermometers have been designed and manufactured.
Basic Introduction to Power Amplifier09 January 2026
Power amplifier refers to an amplifier that can generate the maximum power output to drive a certain load (such as a speaker) under a given distortion rate. The power amplifier plays a pivotal role of "organization and coordination" in the entire audio system, and to a certain extent dominates whether the entire system can provide good sound quality output.
Diode Basis: Symbol, Types and Applications09 January 2026
Hello everyone, I am Rose. Today I will introduce diode to you. A diode is an electronic device made of semiconductor materials (silicon, selenium, germanium, etc.). It has unidirectional conductivity, that is, when a forward voltage is applied to the anode and cathode of the diode, the diode conducts. When a reverse voltage is applied to the anode and cathode, the diode is turned off.
What is a Voltage Controlled Oscillator?09 January 2026
Voltage controlled oscillator (VCO) refers to an oscillator circuit whose output frequency corresponds to the input control voltage. The operating state of the oscillator or the component parameters of the oscillation circuit are controlled by the input control voltage. The frequency of the VCO has a linear relationship with the control voltage. It is an important part of PLL.
What is a Decoder?09 January 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.
What is a Knock Sensor?08 January 2026
Hello everyone, I am Rose. Welcome back to the new post today. I will introduce Knock Sensor to you. The knock sensor is a small "listening" device in or on the engine that detects abnormal vibrations and sounds coming from the engine block.
Introduction to EPROM and EEPROM08 January 2026
EPROM (Erasable Programmable Read-Only Memory) is a kind of ROM memory with erasable function and can be reprogrammed after erasing. Before writing, the contents inside must be irradiated with ultraviolet rays on the transparent window on its IC card to clear it. EEPROM (Electrically Erasable Programmable Read-Only Memory), a memory chip that does not lose data after power failure. EEPROM can erase the existing information and reprogram it on the computer or special equipment.
What is a Digital Potentiometer?08 January 2026
Digital potentiometer, also known as CNC programmable resistor, is a new CMOS digital and analog mixed signal processing integrated circuit that replaces traditional mechanical potentiometer (analog potentiometer). The digital potentiometer is controlled by a digital input and produces an analog output. Depending on the digital potentiometer, the maximum tap current can range from a few hundred microamps to a few milliamperes.
Introduction to IC Packaging08 January 2026
In recent years, IC packaging technologies have emerged and new terms have emerged. There are at least a few dozen IC packaging-related names that can be listed.
Emerging Storage Technologies: MRAM, RRAM, and PCRAM08 January 2026
The semiconductor industry is turning to emerging memories that offer higher storage performance, lower cost, and the ability to move toward process miniaturization. Three of these memories stand out -- MRAM, RRAM, and PCRAM.
What is an ASIC Chip?07 January 2026
ASIC (Application Specific Integrated Circuit) is a special-purpose integrated circuit, which is an integrated circuit designed and manufactured in response to specific user requirements and the needs of a specific electronic system.
Introduction to DDIC (Display Driver IC)07 January 2026
Driver IC is an integrated circuit chip that controls the switching and display method of LCD panels and AMOLED panels. With the increase of panel display resolution and data transmission speed, the requirements for driver ICs are also increasing.
