Switch-mode Power Supply Basics14 December 2020
Switched-mode Power Supply (SMPS), also known as switching converter, is a high-frequency electric energy conversion device and a type of power supply. Its function is to convert a level of voltage into the voltage or current required by the user through different forms of architecture.
What is Sequential Logic?15 October 2020
Sequential logic is an important part of digital logic circuit, which is mainly composed of storage circuit and combinational logic circuit. Sequential logic is also called sequential logic circuit. It is different from other circuits that we are familiar with. Its output state at any time is determined by the input signal and the original state of the circuit at that time, and its state is mainly memorized and represented by the storage circuit.
What is an LTPO Display?08 October 2021
LTPO display is called Low Temperature Polycrystalline Oxide Display. At present, the two main backplane technologies for the small size of OLEDs are LTPS and oxide. LTPO is a new type of backplane technology that combines the advantages of these two technologies to achieve higher charge mobility, stability, and scalability at low production costs.
What is Oscilloscope?24 September 2021
An oscilloscope, formerly known as an oscillograph, is an instrument that graphically displays electrical signals and shows how those signals change over time. This article will introduce it in four aspects.
What is Graphics Processing Unit (GPU)?18 October 2021
Hello everyone, I am Rose. Welcome back to the new post today. The graphics processing unit (GPU), also known as the visual processor, display core, or display chip, is a type of microprocessor that specializes in image processing on personal computers, workstations, gaming consoles, and mobile devices (such as tablets and smartphones). After reading this article, you will have a clear understanding of GPU.
What is Gallium Nitride(GaN)?19 January 2021
GaN is a very stable compound and a hard high melting point material with a melting point of about 1700°C. GaN has a high degree of ionization, which is the highest (0.5 or 0.43) among III-V compounds. Under atmospheric pressure, GaN crystals generally have a hexagonal wurtzite structure. It has 4 atoms in a cell, and the atomic volume is about half of GaAs. Because of its high hardness, it is also a good coating protection material.
What is an Integrated Circuit (ICs) and Why Integrated Circuit is shortage?23 September 2021
An Integrated Circuit(IC), or we can call it IC, chip, or microchip is a small semiconductor-based electronic device minuscule chip consisting of fabricated transistors, resistors, and capacitors, and other metallic connections required for a complete electrical circuit. In this article, we will discuss it in five aspects.
