An Overview of Top Semiconductor Companies10 March 2020
The widespread use of semiconductors has changed our way of life. With the proliferation of electronic equipment, companies manufacturing semiconductors are booming.
Analysis of Resistors in Series and Parallel26 February 2020
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
Introduction to DC Amplifier11 January 2021
An amplifier that can amplify DC signals is called a DC amplifier. A DC amplifier amplifies a DC signal or an alternating signal that changes very slowly with time.
Understanding the Low Noise Amplifier (LNA)20 March 2025
A low noise amplifier is an amplifier with a very low noise figure. It is generally used as a high-frequency or intermediate-frequency preamplifier for various types of radio receivers, as well as amplifying circuits for high-sensitivity electronic detection equipment.
What are the Applications of Filters?23 October 2021
Filtering is a basic and important technique in signal processing. Using filtering techniques, the desired signal can be extracted from various signals and unwanted interference signals can be filtered out. A filter is an important component in the frequency domain analysis of a signal.
Introduction to Synchronous Counter and Asynchronous Counter31 March 2025
The counter is mainly composed of flip-flops. According to the flip order of flip-flops, the counter can be divided into synchronous and asynchronous.
Solid-state Drive (SSD): Classification and Architecture22 May 2021
A solid-state drive (SSD) is a hard drive made of solid-state electronic memory chip arrays. SSD is composed of a control unit and storage unit (FLASH chip, DRAM chip). Solid-state drives are widely used in many fields such as military, vehicle, industrial control, video surveillance, network monitoring, network terminals, electric power, medical treatment, aviation, navigation equipment, and so on.
Introduction to Types of Diodes13 March 2020
According to different purposes, diodes can be divided into rectifier diodes, detection diodes, Zener diodes, varactor diodes, photodiodes, light-emitting diodes, switching diodes, fast recovery diodes, etc.
What is Regulated Power Supply?08 January 2021
Regulated power supply is an electronic device that can provide stable AC or DC power to the load, including AC regulated power supply and DC regulated power supply.
Introduction to Semiconductor Devices02 March 2020
Semiconductor devices are electronic devices with conductivity between a good conductor and an insulator. It uses the special electrical characteristics of semiconductor materials to accomplish specific functions such as generate, control, receive, transform, and amplify signals, and convert energy.
Introduction to Types of Oscillator Circuits20 February 2021
The oscillator operates on the theory of the oscillation and it is a mechanical or electronic unit. The periodic difference between the two items is dependent on the variations in the electricity. The oscillations are used in the watches, clocks, metal detectors and in many other applications use the oscillators.
Introduction to Photonic Integrated Circuits and PIC Technology09 April 2020
The concept of the photonic integrated circuit is similar to the concept of electronic integrated circuits. However, electronic integrated circuits integrate transistors, capacitors, resistors, and other electronic devices, while PIC integrates various optical devices or optoelectronic devices, such as lasers, electro-optical modulators, photodetectors, optical attenuators, optical multiplexers/demultiplexers, and optical amplifiers.
