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

    Miniaturized ultrasonic receivers are designed for efficient powering of implantable medical devices with reconfigurable power loads. Design parameters that affect the efficiency of these receivers under highly variable load conditions, including piezoelectric material, geometry, and operation frequency, are investigated. Measurements were performed to characterize electrical impedance and acoustic-to-electrical efficiency of ultrasonic receivers for off-resonance operation. Finally, we propose, analyze, and demonstrate adaptive matching and frequency tuning techniques using two different reconfigurable matching networks for typical implant loads from 10 [Formula: see text] to 1 mW. Both simulations and measurements show a significant increase in total implant efficiency (up to 50 percentage points) over this load power range when operating off-resonance with the proposed matching networks.

    Abstract

    Microwave-induced thermoacoustic (TA) imaging combines the soft-tissue dielectric contrast of microwave excitation with the resolution of ultrasound for the goal of a safe, high resolution, and possibly portable imaging technique. However, the hybrid nature of this method introduces new image-reconstruction challenges in enabling sufficient accuracy and segmentation. In this paper, we propose a segmentation technique based on the polarity characteristic of TA signals. A wavelet analysis based method is proposed to identify reflection artifacts as well. The time-frequency feature of the signal is used to assist differentiating artifacts. Ex vivo verification with experimental data is also provided.

    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.
