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.
Introduction to Inductive Reactance16 April 2021
Alternating current can also pass through the coil, but the inductance of the coil has an obstructive effect on the alternating current. This obstruction is called inductive reactance.
What is a Fixed Inductor?15 April 2021
Fixed inductors are a classification of inductors according to their structure, and fixed inductors are commonly used inductive devices. An inductor with a fixed inductance is called a fixed inductor (or a fixed coil), and it can be a coil with a single layer, multiple layers, honeycomb type, or a magnetic core. These coils are winded on the magnetic core using a wire of corresponded diameter and they are packaged with epoxy resin or plastic according to the inductance and the maximum DC operating current.
