Current Research and Scholarly Interests


Our work covers circuit/system design in three general areas of 1) mm-Wave and THz, 2) Biomedical, and 3) Ultra-Low Power Electronic sensors.

In the high-frequency domain we design systems that handle information flow. On one end this focuses on the development of sensors and devices that enable next-generation interfaces (e.g., radar system design for human-computer interfaces). On the other end we work one next-generation extremely high-throughput wireless and wireline “pipelines” that facilitate information flow on the network.

On the biomedical front we explore system design for emerging and hybrid medical imaging modalities, apply advanced electrical/electromagnetic interface solutions to bio-sensing applications, and investigate new technologies for wireless implants.

In the sensors area we focus on architectural solutions that enable radically-miniaturized sensors. Other topics include power delivery, energy storage, ultra-low power circuit design, asymmetric communication systems, and antenna interfaces.

Example topics include:

1) High-Frequency Circuits and Systems:
- Terahertz generation/detection and high-frequency systems.
- Wideband systems.
- Phased-array systems and architectures. Array imagers.
- Low-power electronics for sensor applications.
- High-throughput communication systems.
- Optoelectronics.

2) Bio-Medical Applications:
- Microwave/millimeter-wave imaging.
- Physics of medical imaging. Multi-modality imaging techniques.
- Biomedical sensors and actuators.

3) Sensors and Electromagnetic Interfaces:
- Integrated antennas. Co-design of antennas and electronics. Antentronics.
- Remote sensing, power delivery and RFIDs.
- Medical Implants

    Abstract

    This paper introduces a silicon-based imaging array for remote measurements of complex permittivity of tissue. Using a coherent pulsed measurement approach, this time-frequency resolved technique recovers the three dimensional mapping of electrical properties of the subject in the microwave/millimeter-wave frequency spectrum. Some of the major challenges in the design of the system are described. Initial measurement results from the prototype high-resolution transmitter fabricated in a 0.13 μm SiGe process are described. The transmitter achieves pulse widths suitable for millimeter-level accuracy imaging.
