Low-Energy Analog Hardware Security for High-Performance Data Communications: Data security is an indispensable component of any communication link. Data security is typically accomplished by bit-by-bit digital encryption which is inherently a high-energy and slow process. To mitigate these problems, we are pioneering low-energy analog encryption that can be implemented within the analog front-end of a data communication transceiver to encrypt the data before the transmission. These techniques rely on analog properties of the modulated waveforms to protect the data in the analog domain. This way, the energy-hungry digital signal processing (DSP) units can be eliminated and the data can be protected with minimal energy and delay overhead to the system.
High-Performance Trusted RF and Analog Integrated Circuits: Verifying the authenticity of custom integrated circuits (ICs) is critical to build and maintain trust in System-on-Chips (SoCs). Unlike conventional solutions which rely on high-entropy digital functions to implement trust features in SoCs, we take advantage of process artifacts to create unique device fingerprints needed to authenticate the device.
Low-Energy Interface Electronics for Smart Connected Sensors: Energy-efficient high-performance interface circuits are key enablers in developing smart connected sensor networks. Here, we use innovative energy-efficient low-noise circuit design techniques along with ultra-low power (ULP) connectivity solutions to create connected sensor nodes needed for such networks.
Robust power and data transfer for biomedical implants: We focus on the design of biosafety (Electric Field and SAR)-constrained power delivery devices for biomedical implants. We investigate and propose design methodology from an analytical viewpoint with an eye on optimizing power telemetry for this emerging technology. Capacitive link has simpler/planar structures, exhibits large bandwidth, offers reduced EMI, and is microfabrication compatible. This paves the way for our data communication research intended for biomedical implants. Ex vivo measurements are continuously being performed in our state of the art lab-setting.
