Research on Ultra-High-Speed Signal Acquisition and Signal Integrity Processing Technology

As electronic systems evolve towards greater bandwidth, higher transmission rates, and enhanced computing power, the demand for platforms with ultra-high-speed signal acquisition capabilities has become increasingly urgent. Concurrently, technologies for comprehensive signal integrity processing, monitoring, feedback evaluation, and optimization have emerged to complement these platforms. The synergistic development of these capabilities drives effective improvements in high-speed processing technologies, promoting rapid advancements in ultra-high-speed sampling, storage, transmission, and signal integrity-related applications across China's industry chain. This study focuses on ultra-high-speed signal acquisition and signal integrity processing technology based on a self-developed 80 GSa/s (Giga-Samples per second) Analog-to-Digital Converter (ADC) chip. Extensive software-based data processing significantly enhances measurement precision, processing accuracy, and computational efficiency, enabling high-speed signal transmission and processing at an 80 GSa/s sampling rate. For signal integrity processing, conditioning circuits serve as key components, while traceability algorithms form the core of the system. The displayed values are the results of algorithmic calculations, ensuring data accuracy and reliability.
