This paper presents a high conversion coefficient RF front end of an ultra-low power RFID tag, and proposes a new method of more efficient adaptive Q factor tuning and input impedance matching. The Q factor adaptive tuning method makes the front end easier to wake up with limited power, and the adaptive matching method makes the power transmission from antenna to chip more efficient. The conversion...
