Dr. Wang worked for the Institute of Applied Electronics, Mianyang, China, where he was promoted to Principal Engineer in charge of high-power microwave research activities. After receiving his Ph.D. in 2004, he served on the faculty of Southern Illinois University Carbondale for two years before joining Clemson University.
Dr. Wang’s research focuses on integrated high-frequency systems and their applications. We are currently developing network analyzer on-chip (NAoC), high-speed analog-to-digital converters (ADCs), high-frequency nanofluidics, and high-frequency devices incorporated with patterned ferromagnetic materials.
• High-speed integrated circuits and systems: NAoC and ADC
Vector network analyzers (VNAs) are indispensable for high-frequency characterization and analysis of electronic devices, circuits and systems. They are also widely used in other areas, such as material science, biology and chemistry. Commercial VNAs are powerful, yet bulky, expensive and user-unfriendly. Based on radio-frequency (RF) CMOS technology, we are developing NAoCs for various applications, including micro-total-analysis-systems (µTAS). ADCs are critical for many applications. Unfortunately, the speed of ADCs is limited in CMOS technologies even though THz devices are in sight. Based on terahertz (THz) pulses and on-chip spatial sampling, we are developing CMOS ADCs that rival optical approaches in speed and resolution.
• High-frequency microfluidics and nanofluidics
Microfluidic and nanofluidic devices are ideal for integration into a µTAS or a lab-on-a-chip system for analytical separations and determinations of cells and biomolecules (e.g. DNAs and proteins). High-frequency electromagnetic waves, from lower radio-frequency to THz waves, have many unique properties as label-free, non-intrusive sensing and analysis approaches for a µTAS. We are developing high-frequency planar microfluidic and nanofluidic devices for biological and chemical applications.
• High-frequency passive devices incorporated with ferromagnetic materials
High-frequency passive devices, such as integrated inductors, are a bottleneck of the dominant CMOS electronics technologies. One possible approach to solve this problem is to incorporate ferromagnetic materials into the devices. We are studying the high-frequency properties of patterned permalloy thin films, including noise properties and dynamics of an individual nano-ferromagnetic structure.
