In the fields of medical equipment, automotive instrumentation, and industrial control, when equipment design involves strain gauges, sensor interfaces, and current monitoring, precision analog front-end amplifiers are often required to extract and amplify very weak real signals and suppress common unwanted signals such as mode voltage and noise.First, the designer will concentrate on ensuring tha...

When designing boards, we tend to pay attention to those parts that seem to be more core and more critical. They may not pay enough attention to those unimportant parts, but these places often bring catastrophic consequences. For example, the power-on time and sequence of the power supply, we need to pay attention to the rise time of the system power supply. Many people don't un...

As single-chip systems are more and more widely used in consumer electronics, medical, industrial automation, intelligent instrumentation, aerospace and other fields, single-chip systems are facing increasing threats of electromagnetic interference (EMI). Electromagnetic compatibility (EMC) covers both the emission and sensitivity of the system. If a microcontroller system meets the following thre...

Speaking of copying board, you may feel that there is no technical content, and the people who have really copied should have a deep understanding -- this is not that simple.PCB copying board has no software , so it can only be measured and drawn with caliper edge, and it’s very slow and its accuracy is also poor. However, It is very easy to copy the board with the software. Generally, it is more ...

How to judge accurately whether the IC in the circuit is working or not , good or bad, is an important content of repairing TV, audio and video equipment. If the judgment is not accurate, we often have to spend great efforts replacing the new integrated circuit and at the same time the fault still exists, so we should make a correct judgment on the...
