Mahmoud H. Ouda, et al., "5.2-GHz RF Power Harvesting Module in 0.18 μm CMOS for Biomedical Implantable Sensors" IEEE Transactions on Microwave Theory and Techniques 61, (5), 2013, 2177. Abstract: A first fully integrated 5.2-GHz CMOS-based RF power harvester with an on-chip antenna is presented in this paper. The design is optimized for sensors implanted inside the eye to wirelessly monitor the intraocular pressure of glaucoma patients. It includes a five-stage RF rectifier with an on-chip antenna, a dc voltage limiter, two voltage sensors, a low dropout voltage regulator, and MOSCAP based on
