A User Guide to Automotive Relay
30 July 2021
A relay is an automatic control device whose output will change leaps and bounds when the input reaches a certain value. Automotive relays are relays used in automobiles. This type of relay has high switching load power, high shock resistance, and vibration resistance.
What is Resistor?
02 November 2021
Hello, I am Rose. Weilcome to the new post today. Today I will introduce resistor to you. Resistor is one of the three main passive components of electronics, along with inductors and capacitors; from an energy standpoint, resistance is an energy-consuming component that turns electrical energy into heat.
What is a MOSFET?
16 April 2021
MOSFET, short for Metal-Oxide-Semiconductor Field-Effect Transistor, is a field-effect transistor that can be widely used in analog circuits and digital circuits. MOSFETs can be divided into N-channel type with the majority of electrons and P-channel type with the majority of holes according to their "channel" polarity. They are usually called NMOSFET and PMOSFET.
MIT Technology Review Officially Released 2022 Top 10 Breakthrough Technologies in the World
26 April 2022
In the past year or two, the world we live in has undergone an unprecedented and dramatic transformation.
What is a DC-to-DC Converter?
23 April 2021
DC-DC converter, also known as a DC-to-DC converter or DC transformer, is a circuit or electromechanical device that converts electrical energy. It can convert a direct current (DC) power source into a direct current power source (or approximate DC) of different voltages. Its power range is from very low (small batteries) to very high (high-voltage power transmission). The output voltage of some DC-DC converters has the same reference point as the input voltage, while the output voltage of some DC-DC converters is isolated from the input voltage.
A Simple Method to Build a Programmable Oscillator
27 May 2022
Hello, this is Candy. Nice to meet you. Digital potentiometers (digiPOT) are versatile and can be used for a variety of tasks, including filtering and generating AC signals. However, depending on the application, the frequency must occasionally be able to fluctuate and be altered. Programmable solutions that permit frequency change through the appropriate interface are quite handy and, in some situations, extremely beneficial to the development of such designs. Using digiPOT, this article shows how to make a programmable oscillator in which the oscillation frequency and amplitude may be modified independently of one another.
Differential Amplifier vs Current Sense Amplifier
07 April 2022
Hello everyone, I am Rose. Welcome to the new post today. Today I will compare two amplifier to you. Differential amplifier and current sense amplifier.
MEMS Basics: System Features and Classifications
11 June 2021
MEMS, also called micro-electro-mechanical system or micro-system, refers to high-tech devices with dimensions of a few millimeters or even smaller. The internal structure of MEMS is generally on the order of micrometers or even nanometers. A micro-electromechanical system is a micro-device or system that integrates micro-sensor, micro-actuator, micro-mechanical structure, micro-power supply, micro-energy, signal processing and control circuit, high-performance electronic integrated device, interface, and communication.
50 Frequently Asked Questions about PCB Layout [Q&A]
16 November 2021
In the design of electronic products, PCB layout and routing is an important step, and the quality of PCB layout and routing will directly affect the performance of the circuit.
How Fast is Wi-Fi 6?
07 June 2021
Wi-Fi 6 ( IEEE 802.11.ax) is the sixth-generation wireless network technology and the name of the Wi-Fi standard. It is a wireless local area network technology created by the Wi-Fi Alliance based on the IEEE 802.11 standard. Wi-Fi 6 will allow communication with up to 8 devices with a maximum rate of 9.6Gbps.
What is Band Pass Filter?
17 November 2021
Hello everyone, I am Rose. Today I will introduce band pass filter to you. A band pass filter is defined as a circuit that permits a signal to flow between two frequencies.
What is Low Pass Filter
18 November 2021
Hello, today I will introduce low pass filter to you. A low-pass filter (LPF) is a filter that allows low-frequency signals to pass while attenuating high-frequency sounds. The frequency response of a low-pass filter is mostly determined by the low-pass filter's design.
