Introduction to IC Packaging20 August 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.
Characteristics and Working Principle of IGBT31 October 2025
IGBT, Insulated Gate Bipolar Transistor, is a composite fully controlled voltage-driven power semiconductor device composed of BJT (bipolar transistor) and IGFET, (Insulated Gate Field Effect Transistor). It has the advantages of both the high input impedance of MOSFET and the low on-voltage drop of GTR.
Introduction to TTL and CMOS Logic Gate Circuits24 November 2025
Electronic circuits that implement basic and common logic operations are called logic gate circuits. TTL and CMOS logic gate circuits are 2 typical types. Read this to learn their structure and features.
How does a Photodiode Work?15 August 2020
A photodiode is a special diode (light-receiving device) that converts optical signals into electrical signals.It has a pn junction, and its shell has a window with glass for light penetration.So how does it work and how do we use it? Read this article to find the answer.
Rectifier Diode: Function and Circuit12 August 2020
Rectifier Diode is a semiconductor device used to convert alternating current to direct current.It has obvious unidirectional conductivity, and can be made of materials such as semiconductor germanium or silicon. This article gives you a brief introduction to rectifier diodes.
Understanding Computer Memory: From SIMM and DIMM to DDR523 May 2025
DIMM, Dual in-line memory module, is a memory stick that appeared after the launch of Pentium CPU, which provides 64-bit data channels.
Is there a Limit to the Chip Process Node?02 November 2021
Process node refers to the spacing between circuits within an integrated circuit, specifically, the line width of the gate in the transistor structure, which is the value in the XXnm process. The narrower the width, the lower the power consumption.
8051 Microcontroller: History, Architecture, Applications, and Features20 February 2021
The 8051 Microcontroller Introduction and some of its basic features are discussed in this article.
Analysis of Resistors in Series and Parallel12 June 2026
Several resistors are connected at a time to form a circuit without branches in the middle, which is called a resistor in a series circuit. And a circuit that connects two or more resistors between two points in a circuit with the same voltage at both ends of the resistor is called a resistor in a parallel circuit. The following mainly focus on the circuits, calculation methods, fault characteristics and fault treatment of resistors in series and parallel. And the final part introduces a concept-- ESR, which is related to series resistors and capacitors
What is a Polypropylene Capacitor?08 November 2021
A polypropylene capacitor is a kind of capacitor with a very stable electric capacity. It is often used in applications requiring very precise capacitance and can replace most polyphenylene or mica capacitors.
