I am Kevin Chen, I graduated from University of Electronic Science and Technology of China in 2000. I am an electrical and electronic engineer with 23 years of experience, in charge of writting content for ICRFQ. I am willing use my experiences to create reliable and necessary electronic information to help our readers. We welcome readers to engage with us on various topics related to electronics such as IC chips, capacitors, resistors, inductors, circuit breakers, diode, transistor, module, relay, opticalcoupler, connectors, PCBs, etc. Please feel free to share your thoughts and questions on these subjects with us. We look forward to hearing from you!
Image source: Pixabay Storage is a crucial part of any embedded system, especially given the level of intelligence and features manufacturers are embedding into smaller devices. A Memory management controller (MCU) is a cost-effective way to manage all system memory in an embedded device. eMMC integrated circuit (IC) is often known as an embedded multimedia…
Image Source: Unsplash An EEPROM or Electrically Erasable Programmable Read-Only Memory is an IC that can be used to store non-volatile data. It is a special type of ROM that can be reprogrammed by an external source. This means you can set the IC once and it will remember that setting even if there has…
Image source: Pixabay Digital memory or dynamic random access memory (DRAM) is a type of computer memory that can be accessed randomly, i.e., any byte can be read or written or both with one operation. It is a volatile form of random-access memory (RAM) that saves data temporarily when the computer is turned off. DRAM…
Image Source: FreeImages Power management is a major challenge in modern electronic devices. As smaller chips are able to do more, they also consume less power. And that means battery life is getting shorter. Manufacturers need to find smarter ways to manage power usage so their devices can last longer. Fortunately, there are industry standard…
Image Source: FreeImages Probably you know what a potentiometer is. It is a type of variable resistor that is used for balancing the potential difference across a circuit. A potentiometer works by acting as an adjustable voltage divider between an input voltage source and the ground. By adjusting the “pots” or “control” on the potentiometer,…
Radio frequency integrated circuits, or RF ICs , are microelectronic components with multiple functions that can be used in a single device. An RF IC is a type of chip that has been manufactured to meet specific performance and usage needs. These chips are widely used in communications, broadcasting, wireless networking, radar, and other…
Obviously, you know how a manual switch operates. You turn it on and off to control what you want it to do. In most cases, to start off a circuit or stop. But, what really happens in complex or embedded electronic devices? We know that these devices operate using logical conditions. Integrated circuits are used…
Image Source: ImageSource Opto-coupler is an electrical component that can be used to transfer electrical signals while remaining isolated from each other. This isolation is important because the two circuits being bridged may have different voltage potential or they may produce electromagnetic interference that would interfere with other parts of the circuit. Optocouplers are similar…
When you see the word ‘filter’, the first thing that should come into your mind is elimination. You will probably assume that something should be removed from the rest. In the field of electronics and communication, a device may receive or transmit loads of signals. Not all the signals are desired to be used. And…
Image source Quora There are different electronic components that are added to integrated circuits. Resistors, capacitors, and diodes are just some of these components. But there is one component, no matter how important it is, most people tend to avoid adding it to the IC. That is the inductor. So, why is it always avoided?…
