XINGDA CHEN

“COCOON” project

• Achieved multi oscillators synchronization on a wall using frequency pulling.
• Achieved PLL locking and precise RF output with cheap ceramic reference oscillator
• Improved multi-static, FM, backscatter communication range by designing a novel backscatter environment.
• Reduced cost of radio front fot IoT application

Research Assistant

• Developed virtual radio environments using SDR and USRP
• Designed and characterized more than 10 PCB prototypes regarding radio communication and RF sensing
• Assisted with multiple low power communication and RF sensing prototypes.
• Performed set up, operation, maintenance/repair, modification, circuit testing and calibrating operating systems.

NMR Echo

• Designed and manufactured a coffee cup size nuclear magnetic resonator that is portable, battery ran, and Bluetooth enabled.
• Outlined design requirements, BOMs, functional specifications and reports to document development processes.
• Translated broad spectrum project requirements to detailed hardware architecture design concepts.

Implantable backscatter chip

• Designed and simulated an RF power harvested, backscatter chip using Candence for implantable bio sensing purpose.
