Near Field Communication (NFC) Explained: Working and Applications24 May 2021
Near Field Communication (NFC) is evolved from the integration of non-contact radio frequency identification (RFID) and interconnection technology. Devices using NFC technology can exchange data when they are close to each other. By integrating the functions of inductive card readers, inductive cards, and point-to-point communication on a single chip, applications such as mobile payment, e-ticketing, access control, mobile identification, and anti-counterfeiting can be realized by using mobile terminals.
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.
Optical Image Stabilization (OIS) Explained: Types and Working21 May 2021
In cameras or other imaging instruments, optical image stabilization (OIS) refers to the setting of optical components to avoid or reduce instrument jitter in the process of capturing optical signals, thereby improving image quality.
What is AMOLED?25 April 2021
AMOLED is an active-matrix organic light-emitting diode. AMOLED is a display technology for mobile devices, digital cameras, media players, and television. It uses active matrices to address pixels and uses a special type of film technology, wherein the organic compound forms an electroluminescent material.
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.
What is a Printed Circuit Board?22 April 2021
A printed circuit board(PCB) is the provider of electrical connections for electronic components. Printed circuit boards are often represented by "PCB", but cannot be called "PCB boards".
RF Modulator: Working Principle and Development Trend21 April 2021
An RF modulator is an electronic device that provides a baseband signal, which is used to convert radio frequency resources.There are many RF modulators available, but all functions work in a similar way.
What is an Accelerometer Sensor?20 April 2021
An accelerometer sensor is a sensor that can measure acceleration. It is usually composed of masses, dampers, elastic components, sensitive components, and adaptive circuits. In the process of acceleration, the sensor obtains the acceleration value by using Newton's second law, measuring the inertial force on the mass block. According to the different sensitive components of the sensor, common accelerometer sensors include capacitive, inductive, strain gauge, piezoresistive, piezoelectric and so on.
How does Lidar Work?20 April 2021
Lidar or LiDAR is an abbreviation for Light Detection and Ranging. Lidar is a radar that uses a laser as a radiation source. Lidar is the product of a combination of laser technology and radar technology.
What is a Force Sensor?19 April 2021
Force sensor (force sensor) is a component that converts the magnitude of force into related electrical signals. The force sensor can detect mechanical quantities such as tension, pressure, weight, torque, strain, and interior stress. It has become indispensable core component of power equipment, engineering machinery, various working machines, and industrial automation systems.
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.
What is a Reed Relay?16 April 2021
A reed relay is a type of relay that uses an electromagnet to act directly on the reed-like contact of a reed switch contained within a glass envelope, typically bringing the reeds together to make contact when the electromagnet is powered.
