Basic Introduction to Power Amplifier
10 October 2020
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.
STM32U5: The Most Complex Low-power MCU
19 January 2022
In March 2021, STMicroelectronics (ST) announced the STM32U5, and in September the first STM32U5 models were officially mass-produced, meaning that ST gave birth to the first ultra-low-power microcontroller to achieve both PSA Level 3 and SESIP 3 safety certifications.
Buffer Amplifier | Operating Principle, Advantages, and Applications
21 July 2025
This guide will talk in detail about the buffer amplifier to clarify all your concepts around its working principle and applications.
Introduction to Distribution Transformer
24 February 2021
Often known as a common kind of isolation transformer is a distribution transformer. The key purpose of this transformer is to adjust the high voltage to the standard voltage to be used in electrical power delivery, such as 240/120 V. There are distinct types of transformers available in the delivery chain, such as single phase, 3-phase, underground, pad-mounted, pole-mounted transformers.
Design and Implementation of High Frequency Inverter for Printer Based on IR2110
13 April 2022
Hello everyone, I am Rose. Welcome to the new post today.In this article, the design of an independent inverter power supply based on SPWM technology is completed by combining the principle of the inverter circuit with the single-chip technology.
Introduction to TFT Displays
29 August 2020
TFT Display is a thin film transistor type liquid crystal display. TFT liquid crystal is equipped with a semiconductor switch for each pixel, and each pixel can be directly controlled by dot pulses. So each node is relatively independent and can be continuously controlled, which not only improves the response speed of the display screen, but also allows precise control of displaying color gradation, so the color of TFT liquid crystal is truer.
-5V, -3V, How is the Negative Voltage Generated? Attached Circuit Analysis and Scheme
13 September 2022
Hello everyone, I am Rose. Welcome to the new post today. Today I will introduce negative voltage to you. Including its definition, how it was generated and its meaning.
Introduction to Acceleration Sensors
28 July 2020
An acceleration sensor is a sensor that can measure acceleration. It is usually composed of a mass block, damper, elastic element, sensitive element and an adaptive circuit. During the acceleration process, the sensor uses Newton's second law to obtain the acceleration value by measuring the inertial force applied to the mass. According to the different sensitive elements of the sensor, common acceleration sensors include capacitive, inductive, strain, piezoresistive, and piezoelectric type.
Parallel Plate Capacitor: Features, Working Principle and Applications
30 January 2021
A parallel plate capacitor is defined as a capacitor that can be created using the arrangement of electrodes and insulating material such as a dielectric. Two conducting plates that are separated by a dielectric material are included in the capacitor. The conducting plates here act as electrodes.
Introduction to Bandstop Filter
28 January 2021
There are numerous filter types, including high-pass filters, low-pass filters, bandpass filters, and filters for bandstops. The high-pass filter only allows frequencies greater than the cut-off frequency, and the low-pass filter allows frequencies smaller than the cut-off frequencies. A specific band of frequencies will be permitted by the bandpass filter and a band stop filter will reject a specific band of frequencies. An overview of the bandstop filter is discussed in this article.
Introduction to Flash Memory
23 July 2020
Flash memory is a non-volatile computer memory storage medium that allows multiple erases or writes during operation. This technology is mainly used for general data storage, as well as the exchange and transmission of data between computers and other digital products, such as memory cards and USB flash drives.
