Research
The ultimate goal of our research is to develop medical devices capable of accurately measuring multiple biomarkers in human samples for disease diagnosis and monitoring. Achieving this goal involves addressing numerous challenges, including biosensor non-specificity, bioassay matrix effects, circuit noise and nonlinearity, device miniaturization, and system-level integration. To tackle these challenges effectively, we divide our efforts into multiple interconnected projects spanning circuit design, system architecture, and biochip integration. Through this multidisciplinary approach, we aim to deliver clinically useful breakthroughs that advance healthcare technologies.
Data Converters (ADC/DAC)
High performance data converters are critical for sensing, audio, and wireless communication applications. Our lab researches on high resolution ADCs for sensing and high speed DACs for wireless communication. Our data converters are application specific integrated circuits (ASIC) rather than general purposes ADC/DAC.
Sensor Analog Front-End (AFE)
Various types of sensors need analog front-end (AFE) circuits to acquire data accurately and quickly with low power consumption. Our lab explores new circuit architectures (direct sensor to digital converter) that simplifies the standard AFE architecture (sensor bias + instrumentation amplifier + ADC) to achieve better performance and lower power.
Biosensor Circuits and Systems
Biosensor systems aim to bring clinic based medical instruments to portable or wearable devices for point-of-care diagnostics and disease tracking. This interdisciplinary field focuses on combining biosensors and electronic systems together to overcome challenges from both biosensing and circuit implementation.
