5.8 GHz Near Field Power Harvesting Circuitry Implemented in 14 nm CMOS Technology

This paper summarizes the simulated and measured performance of major analog blocks contained in an advanced RFID system designed and fabricated in Global Foundries 14nm FinFET technology. These analog blocks were designed and built in support of the DARPA Supply Chain Integrity in Electronics Defense program which aims to establish electronics component traceability in order to eliminate counterfeit electronics from defense and commercial supply chains. The 14nm node was chosen to meet the size goal of the program, 100μm X 100μm, while achieving a high level of functionality which includes power harvesting and regulation, load modulation communications, a tamper sensor, a unique ID, and an authentication protocol that includes a 256 advanced encryption standard encryption engine, a split 256 bit key, and random number generator.
