A coil is integrated inside an implanted antenna in order to support inductive charging. The implanted antenna has been designed for wireless data telemetry at 400 MHz region and radiating wireless charging at 915MHz. The antenna-coil system is embedded into a three-layer canonical model of human arm. In the inductive charging case an external transmitting coil is considered while in the radiating...
A long range, low power UHF RFID analog front-end suitable for batteryless wireless sensors has been designed using a low cost 0.35 μm CMOS standard process. The proposed front-end architecture allows the implementation of power management techniques that together with the power optimized blocks such as voltage limiter, ASK demodulator... provides a long reading range. The implemented voltage multiplier...
