Shenzhen, China - April 9, 2025 - The 13th China Information Technology Expo (CITE 2025) officially commenced today at the Shenzhen Convention and Exhibition Center (Futian). This year's exhibition spotlights eight core sectors of the electronics information industry, showcasing cutting-edge products and technologies across the entire industrial chain - from smart terminals, wearables, and robotics to low-altitude economy, digital storage, servers, and integrated circuits.
The event brings together 500+ industry leaders, experts, and scholars who will share insights on emerging trends and technical solutions to critical industry challenges, shaping the future of electronic information technology. Over the three-day exhibition, CITE 2025 is expected to:
· Attract 1,000+ exhibitors from 15 countries and regions
· Host 50 summit sessions
· Welcome 60,000 professional attendees
On its opening day, the expo has already garnered extensive coverage from leading global media outlets including Xinhua News Agency, CNR.cn, and Guangming Daily.
At CITE 2025, Professor Huang Lei's research team from Shenzhen University showcased their pioneering variable-threshold one-bit chip technology alongside related products. In recognition of this groundbreaking innovation, the team was honored with the 13th China Information Technology Expo Innovation Gold Award, standing alongside industry leaders including MediaTek, TCL CSOT, and China Great Wall Technology Group - a testament to the robust capabilities of "China's Intelligent Manufacturing."
Professor Huang delivered an invited keynote address titled "Variable-Threshold One-Bit ADC Chip and Radar System Solutions" during the event. The unveiling of the world's first variable-threshold one-bit ADC chip and its companion lightweight radar system represents a significant technological milestone, demonstrating the team's successful breakthrough in high-precision analog-to-digital conversion technology. This achievement underscores Shenzhen University's exceptional innovation capabilities in radar technology research and development.
Independent Innovation: Solving the “Chip Shortage” Crisis
Amid global chip supply constraints and escalating demands for drone radar performance, traditional multi-bit chips face limitations due to high computational loads and storage bottlenecks. Prof. Huang’s team pioneered a one-bit quantization technology with a dynamic threshold mechanism, integrating gain calibration, noise suppression, and adaptive clock design to enhance signal processing efficiency. This breakthrough reduces system complexity without sacrificing accuracy, offering a homegrown solution for mission-critical radar applications.
The Lightweight Revolution: Enabling Diverse Applications
The chip’s compact design enables radar systems to achieve unprecedented size and weight reductions, compatible with drones, vehicles, and microsatellites. Its one-bit architecture maintains superior detection accuracy, imaging quality, and energy efficiency, earning recognition as “one of the most transformative civilian radar technologies” at the China International Aviation & Aerospace Exhibition. Current deployments span aerospace, mapping, and public security sectors.
From Lab to Market: Industry-Academia Collaboration
Dubbed “aerial photography for radar,” the one-bit imaging technology could reshape radar receiver architectures and redefine industry standards. Partnerships with research institutes and enterprises are already accelerating its adoption, with applications in low-altitude monitoring and power grid inspection. Media outlets have hailed the team’s lightweight imaging solutions as a game-changer for smart infrastructure.
The Gold Award underscores the technology’s maturity and industry-wide endorsement, signaling China’s leap from follower to leader in high-end radar chips. Moving forward, the team will advance high-bandwidth one-bit ADC chips and RF integration to drive intelligent unmanned systems and low-altitude economy ecosystems.
