An RF-DC Converter IC With On-Chip Adaptive Impedance Matching and 307- $\mu$ W Peak Output Power for Health Monitoring Applications.

This paper presents an RF-DC converter integrated circuit (IC) with ~307-μW output power capable of powering individual health monitoring systems. The IC is designed with an on-chip adaptive impedance matching network to accommodate a wide input RF power variation and extend the operating frequency range. The system is composed of an antenna, an adaptive impedance matching network, a three-stage f...
