Signal chain chip details: the bridge between the real world and the digital world

What is a "signal chain chip"? We live in an analog world: signals such as sound, voltage, temperature, pressure, and light intensity are all changing continuously. However, most electronic systems - such as mobile phones, smart watches, industrial controllers, and unmanned driving systems - ultimately process and store information using digital logic (0 and 1). The signal chain chip is an intermediary system between this "analog world" and the "digital world". It is responsible for receiving external analog signals, amplifying, filtering, converting, conditioning, and other processing, and finally converting the signal into a data format that can be processed by the digital system.It can be understood as follows: the signal chain is a "pipeline" that receives signals from sensors, filters out impurities, enhances weak signals, transforms signal formats, and then hands over clean s...

Working principle, structural classification, performance parameters, process characteristics, design challenges and application scenarios of ADC chips

1. What is an ADC chip? ADC stands for Analog to Digital Converter. Its function is to convert the "continuously changing" analog signals in the real world (such as temperature, voltage, sound, light, etc.) into "discrete digital signals" (such as binary codes like 010101) that can be understood by computers or digital chips. It can be simply understood as:🧠 The real world speaks "human language" (analog signals)💻 Digital chips only understand "code" (digital signals)ADC is the "translator" between these two worlds. 2. Why is ADC chip important? Almost all physical signals around us are analog, such as ECG signals, sounds collected by microphones, pressure or temperature read by sensors, etc. However, we hope to use digital systems (such as MCU, DSP, FPGA) for processing, calculation, analysis, storage, etc.Therefore, ADC is a necessary link in...

The maturity of IC will bring about a great leap forward in technology, both in terms of design technology.

Advanced integrated circuits are at the heart of KLA-LA’s core developments and control everything from computers to cell phones to digital. While the cost of designing a complex integrated circuit is very high, when spread across products that typically number in the millions, the cost per integrated circuit is minimized. The performance of integrated circuits is huge because small size leads to short paths, allowing low-power logic circuits to be applied at fast switching speeds. Over the years, integrated circuits have continued to move toward smaller form factors, allowing more circuits to be packed into each chip. This increases the capacity per unit area, which allows for lower costs and increased functionality, see Moore's Law, the number of transistors in an integrated circuit doubles every 1.5 years. In short, as the form factor shrinks, almost all indicators ...

This process and the advances expected in the coming years are well described in the International Technology Roadmap for Semiconductors

Advanced integrated circuits are the heart of microprocessors or multi-core processors that control everything from computers to cell phones to digital microwave ovens.
