What is SMT (Surface Mount Technology)?02 December 2021
SMT (Surface Mount Technology) refers to the abbreviation of a series of technological processes that are processed on the basis of PCB. SMT is the most popular technology and process in the electronic assembly industry.
Introduction of 55 ADC and DAC Commonly Used Terms02 December 2021
Hello everyone, I am Rose. Today I will introduce 55 terms of ADC and DAC commonly used terms for you.
Filter Circuit: Types, Characteristics and Principles01 December 2021
The rectifier circuit output voltage is a one-way voltage and cannot be used directly on the electronic circuit. Therefore, it is possible to filter the output voltage, eliminate the AC component in the voltage, and use it to the electronic circuit after DC. In the filter circuit, a device that has special impedance characteristics of AC is mainly used, such as a capacitor, inductor. This article will analyze the various forms of filtering circuits.
What is Power over Ethernet(PoE)?01 December 2021
Hi fellas. I am Rose. Welcome back to the new post today. PoE is a technique that uses an Ethernet wiring system to deliver data signals to IP-based terminal devices (such as IP telephones, wireless LAN access points, network cameras, and so on) while also providing DC power to these devices.
Comprehensive Analysis of Switching Power Supply Circuits30 November 2021
Today we introduce the circuit and principle of switching power supply. This article mainly lists and analyzes the various functional circuits of the switching power supply.
What is First In First Out (FIFO)?30 November 2021
Hello everyone, I am Rose. Today I will introduce FIFO to you. First In First Out is the complete English spelling of FIFO, which means "first in, first out." The term "FIFO" in FPGA or ASIC refers to a memory that stores data in a first-in, first-out manner, and is frequently used for data buffering or high-speed asynchronous data interaction.
What is PLL(Phase Locked Loop)?29 November 2021
PLL (Phase Locked Loop): It is a phase-locked loop or a phase-locked loop, which is used to unify and integrate clock signals to make high-frequency devices work normally, such as memory access data. PLL is used for feedback technology in oscillators. For many electronic devices to work normally, the external input signal is usually synchronized with the internal oscillating signal. Ordinary crystal oscillators cannot achieve very high frequencies due to process and cost reasons. When high frequency applications are required, the corresponding device VCO can be converted to high frequency, but it is not stable, so the phase-locked loop can be used. Realize a stable and high-frequency clock signal.

15 Key Elements of Diode Selection26 November 2021
Hello everyone, I am Rose. Welcome back to the new post today. Diodes are one of the most common components in our circuit boards. So, what factors should be considered when selecting models?
What is GDDR?25 November 2021
GDDR SDRAM is one of the key core components of a graphics card, and its strength and capacity will directly affect the final performance of the card.
What is SPI (Serial Perripheral Interface)?25 November 2021
Hi, fellas. I am Rose. Welcome back to the new post today. The SPI protocol will be introduced today. Motorola's Serial Peripheral Interface (SPI) is an acronym for Serial Peripheral Interface. A full-duplex, high-speed bus protocol.
What is PCB Reflow? High-Speed Signal Reflow Path Analysis24 November 2021
Hello everyone, I am Rose. Welcome back to the new post today. The fact that electrons never stay in one place and must return no matter where the current runs are one of the properties of electron flow. As a result, current flows in the loop at all times, and any signal in the circuit exists as a closed-loop.
