Top Chinese Photoresist Manufacturers Guide07 January 2022
Since the second half of 2020, the global semiconductor industry's prosperity has continued to rise, and the upstream photoresist market is no exception.
Basic Introduction to Hall Effect Sensors28 July 2020
The Hall effect sensor is a magnetic field sensor made according to the Hall effect. The Hall effect is a type of magnetoelectric effect. This phenomenon was discovered by Hall (A.H. Hall, 1855-1938) in 1879 when he studied the conductive mechanism of metals.
What is a Voltage Controlled Oscillator?08 October 2020
Voltage controlled oscillator (VCO) refers to an oscillator circuit whose output frequency corresponds to the input control voltage. The operating state of the oscillator or the component parameters of the oscillation circuit are controlled by the input control voltage. The frequency of the VCO has a linear relationship with the control voltage. It is an important part of PLL.
What is Inertial Measurement Unit (IMU)?30 December 2021
An inertial measurement unit (IMU) is a device that measures three-dimensional linear and angular motion without an external reference, i.e., a device that measures the three-axis attitude angle (or angular rate) and acceleration of an object.
What is a Switched Reluctance Motor?09 July 2024
Switched reluctance motor is a type of speed-regulating motor developed after DC motor and brushless DC motor. Product power levels range from several watts to hundreds of kilowatts, and are widely used in household appliances, aviation, aerospace, electronics, machinery, and electric vehicles.
7 Common Functions of MOSFET Gate Circuits22 January 2022
The gate is the MOSFET's weakest component. It is possible to cause the device or even the system to fail if the circuit is not constructed appropriately. As a result, this article organizes the most popular gate circuits for your reference and discussion, and you are also free to share your own thoughts.
What are Tilt Sensors?19 December 2020
Tilt sensors are often used to measure changes in the horizontal angle of the system. The level from the simple bubble level in the past to the current electronic level is the result of the development of automation and electronic measurement technology.
Introduction to Optical Zoom and Digital Zoom19 June 2021
Optical zoom relies on the structure of the optical lens to achieve zoom, that is, the lens of the camera is moved to zoom in and out of the scene to be shot, and the resolution and image quality will not change. The greater the optical zoom factor, the more distant objects can be captured. Digital zoom uses the processor in the digital camera to increase the area of each pixel in the picture to achieve the purpose of magnification.
What is Gallium Nitride(GaN)?19 January 2021
GaN is a very stable compound and a hard high melting point material with a melting point of about 1700°C. GaN has a high degree of ionization, which is the highest (0.5 or 0.43) among III-V compounds. Under atmospheric pressure, GaN crystals generally have a hexagonal wurtzite structure. It has 4 atoms in a cell, and the atomic volume is about half of GaAs. Because of its high hardness, it is also a good coating protection 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.
Infrared Thermometer: How it Works? How to Use it?12 August 2021
Infrared thermometers are divided into fixed thermometers and hand-held thermometers. They are a kind of thermometer that detects the amount of infrared rays on the surface of an object to achieve temperature measurement.
