On-Chip RF Power Harvesting for Biomedical Implantable Wireless Sensors.
The lecture will be focused RF power harvesting which is highly essential to enable battery-less wireless sensing platforms for many applications. One of the most vital applications is the biomedical implants. In this research work, we present an on-chip RF power harvesting module designed and implemented on standard 0.18 µm CMOS process [1]. This module has been integrated with an on-chip antenna [2] to build a miniaturized 3 x1.5 mm2 System-on-Chip (SoC) for an implantable sensor chip to wirelessly monitor the intraocular pressure of glaucoma patients [3]. It includes a five stage RF rectifier with an on-chip antenna, a DC voltage limiter, two voltage sensors, a low dropout voltage regulator (LDO), and MOSCAP based on-chip storage. To emulate the eye environment in measurements, a custom test setup is developed which comprises plexiglass cavities filled with saline solution. System and circuit design and the measurement setup and results will be discussed. Then the limitation of the designed system will be addressed and motivates for the second part of this research work which is to build an adaptive reconfigurable RF power harvesting module to overcome these limitation.

Salama of KAUST
Biography:
Khaled N. Salama received the B.S. degree from the Department Electronics and Communications, Cairo University, Cairo, Egypt, in 1997, and the M.S. and Ph.D. degrees from the Department of Electrical Engineering, Stanford University, Stanford, CA, USA, in 2000 and 2005, respectively. He was an Assistant Professor at Rensselaer Polytechnic Institute, NY, USA, between 2005 and 2009. He joined King Abdullah University of Science and Technology (KAUST) in January 2009, where he is now a professor, and was the founding Program Chair until August 2011. He is the director of the sensors initiative a a consortium of 9 universities (KAUST, MIT, UCLA, GATECH, MIT, UCLA, Brown University, Georgia Tech, TU Delft, Swansea University, the University of Regensburg and the Australian Institute of Marine Science (AIMS). His work on CMOS sensors for molecular detection has been funded by the National Institutes of Health (NIH) and the Defense Advanced Research Projects Agency (DARPA), awarded the Stanford–Berkeley Innovators Challenge Award in biological sciences and was acquired by Lumina Inc. He is the author of 250 papers and 18 US patents on low-power mixed-signal circuits for intelligent fully integrated sensors and neuromorphic circuits using memristor devices.
