An Analog-to-Digital Converter (ADC) is primarily used to convert continuously transmitted analog signals into digital signals, facilitating rapid processing and analysis of transmitted information by digital systems (such as CPUs and MCUs). Generally speaking, the different quantization mechanisms of ADCs are one of the key factors determining the complexity and performance of ADC design, as … Read more
With the development of technology, RS232 serial communication is still widely used in industry. However, in commercial applications, the USB to UART technology has gradually replaced RS232 serial ports. Most laptops no longer have serial ports. So, how can we achieve communication between a microcontroller and a computer? We only need to add a USB … Read more
In many circuits, small-value resistors are connected in series. Don’t underestimate them; they actually play a significant role. 1. SPI Signal Lines For SPI signals, the series resistor is generally around tens of ohms and has the following functions: 1) Impedance Matching. Since the impedance of the signal source is very low, and there is … Read more
In high-speed digital signal processing (DSP) systems, electromagnetic interference (EMI) is a critical issue that cannot be overlooked. Due to the high-frequency signal processing and complex circuit layouts involved in DSP systems, the electromagnetic environment becomes more complicated, easily leading to signal distortion, system instability, and even functional failure. Therefore, engineers need to understand the … Read more
In PCB design, engineers need to follow a series of principles for layout and routing to create excellent boards. While some principles can be disregarded, there are certain principles that must be adhered to for the stability and safety of the entire system. So, what are the principles that all engineers must follow? 1. Reasonable … Read more

PCB Network City News When it comes to PCB boards, many friends think of how they are ubiquitous around us, from all kinds of household appliances, various components inside computers, to various digital products. Almost all electronic products will use PCB boards. So what exactly is a PCB board? A PCB board is a Printed … Read more
When designing a PCB, I found that many people, especially beginners, do not have a clear understanding of the layers in a PCB. Therefore, today let’s take a look at the differences between the various layers when using the software Altium Designer to create a board. 1. Signal Layer The signal layer is divided into … Read more
Whether it’s a board made by someone else or a PCB board designed and produced by yourself, the first thing to do upon receiving it is to check the integrity of the board, such as issues with soldering, cracks, short circuits, open circuits, and drilling. If the function of the board is relatively strict, it’s … Read more
