要約(英語)：Active rectifier is one of important and indispensable analog circuit for wireless power transfer in applications such as RFID and Near Field Communication (NFC). Active rectifier topology such as cross-coupled and self biased CMOS active rectifiers have been proposed. However, these rectifier topologies only offer good power efficiency at a relatively limited range of input voltage. This paper proposes a new topology of CMOS active rectifier which provides a high power efficiency across a wider range of input voltage compared to conventional topologies. The proposed circuit is designed using high voltage device of 0.18 um CMOS process. Measurement results show an average output voltage and ripple of 1.6 V and 0.0 V respectively for input voltage amplitude of 3V and load resistance of 10 kohm. The frequency of input voltage is 13.56 MHz assuming the carrier frequency of NFC system.
