Abstract :
Process and temperature independent RF frontend design is important for remotely powered RFID tags and wireless sensor systems. Run-to-run process variations can impact the remote powering performance and therefore read range of aforementioned systems. We introduce analysis and propose a design methodology for high-Q switched capacitor matching network for remote powering. The method is demonstrated with a differential drive rectifier topology with -14 dBm of input power at 900 MHz UHF band. Simulation results show the improvement on delivered power up to 42% and extension of the read range of the sensor system up to 19% with utilization of the proposed work.
