Research
The Mixed-Signal Integrated Circuits and Systems (MSICAS) Lab at the University of South Florida develops application-driven integrated circuits and intelligent sensing systems that bridge the physical and digital worlds. Rather than pursuing general-purpose circuit performance in isolation, our research focuses on co-designing analog and mixed-signal circuits, data converters, sensors, and system architectures to address unique requirements of real-world applications. By combining circuit innovation with advanced sensing, energy-efficient electronics, and intelligent systems, we aim to create highly integrated solutions that achieve the right balance of sensitivity, efficiency, robustness, and autonomy for emerging healthcare, electronic, and autonomous-system applications.
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.
