What is an Application-specific Integrated Circuit?13 April 2021
Application-specific integrated circuits are integrated circuits made for specific users or specific electronic systems. The versatility and mass production of digital integrated circuits have greatly reduced the cost of electronic products and promoted the popularization of computer communications and electronic products. However, at the same time, it has also created the problem of the contradiction between general-purpose and special-purpose, and the disconnection between system design and circuit production.
How to Select a Digital Isolator?12 April 2021
A digital isolator is a chip used to make the electronic system have high resistance isolation when signals and analog signals are transmitted, so as to realize the isolation between the electronic system and its users. The reason why designers introduce isolation is to meet safety regulations or reduce ground loop noise.
An Overview of SD Card12 April 2021
The SD (Secure Digital) card is a new generation of memory devices based on semiconductor flash memory. Due to its small size, data transmission speed, hot-swap, and other excellent features, it is widely used in portable devices, such as digital cameras, tablets, and multimedia players, etc.
What is a Ceramic Filter?10 April 2021
Ceramic filter is a widely used filter that uses rigid microporous material as a filter element. It is composed of ceramic, corundum, silicon carbide, sand chip, and so on. It is mainly used in fluidized bed combustion, calcination, power generation through organic waste gasification, building materials, and other fields.
What is a Thermoelectric Cooler?08 April 2021
Thermoelectric Cooler (TEC) is found in many applications that require precision temperature control. The small size of the TEC allows precision thermal control of individual components such as fiber optics, laser drivers, precision voltage references, or any other temperature critical device.
What is Uninterruptible Power Supply (UPS)?08 April 2021
UPS is an uninterruptible power supply containing the energy storage device. It is mainly used to give a part of a device with a higher power stability, providing uninterrupted power supplies.
How does an Inverter Work?06 April 2021
The inverter is a converter that converts DC electric energy into constant frequency and constant voltage AC or Frequency and voltage modulation AC. It is composed of an inverter bridge, control logic, and filter circuit. Inverters are widely used in air conditioners, home theaters, electric grinding wheels, power tools, DVDs, VCD, computers, TVs, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, etc.
What is an Auto Transformer and Its Working?01 April 2021
Auto transformer refers to a transformer whose primary and secondary windings are on the same winding, and the primary and secondary windings are directly connected in series and self-coupled. According to the structure, it can be subdivided into adjustable pressure type and fixed type. Auto-coupling means electromagnetic coupling. Ordinary transformers transfer energy through the electromagnetic coupling of the primary and secondary coils. There is no direct electrical connection between the primary and secondary sides. The primary and secondary sides of the auto transformer have direct electrical connections. Its low-voltage coils It is part of the high voltage coil. Protective equipment such as auto transformers are also used in protective equipment for communication lines.
What is a SAW Sensor? Types, Working and Applications29 March 2021
The SAW (Surface Acoustic Wave) sensor is a new type of micro-sensor that has developed in recent years. It is an acoustic surface wave device as a sensor element that will be measured through the acoustic surface wave device. The speed or frequency of the wave is reflected and converted into the sensor output by the electrical signal.
RGB LED: Circuit, Difference and Application25 March 2021
White LED and RGB LED are the same in essence. They both hope to achieve the effect of white light, but one is directly presented in white light, and the other is made by mixing red, green and blue light. RGB lamps are integrated with the three primary colors. In addition, there are blue LEDs with yellow phosphors, and ultraviolet LEDs with RGB phosphors. On the whole, both have their imaging principles. The colors of some LED backlight panels are particularly clear and vivid, even to the level of high-definition TVs. This situation is exactly the characteristic of RGB, which advertises the characteristics of red as red, green as green, and blue as blue. In terms of color mixing, it has more diversified characteristics.
Analog Switch: Types and Application25 March 2021
The analog switch is mainly to complete the signal switching function in the signal chain. The switching mode of the MOS tube is adopted to realize the switching off or on of the signal link.
What is a Biosensor?23 March 2021
Biosensor is a device that is sensitive to biomass and can convert its concentration into electrical signals. It is an analytical tool composed of a fixed biosensitive material as an identification element, a suitable physiological transducer, and a signal amplifying device. Biosensor has the function of the receptacle and the converter.
