Abstract :
In this paper, a charge-pump type AC-DC converter for RF ID tags is proposed. Since the proposed converter employing novel bootstrap circuits can avoid the threshold voltage drop caused by diode-switches, it can achieve an AC-DC conversion at high efficiency. The SPICE simulations showed that the power efficiency of the proposed converter is more than 85% and the electric power is about 5 mW when an output load is 500Omega. Furthermore, the characteristics concerning power efficiency and ripple voltage are analyzed theoretically
