AC power is available commercially at low cost. DC power is relatively expensive to produce. Therefore a method for changing ac to dc is needed in relatively less expensive way as a source of dc power. The method presented in this paper to convert ac power to dc

Design of 900 Mhz AC to DC converter using native Cmos device of TSMC 0.18 micron technology for RF energy harvest application
free download

RF signal carries very low amount of energy and can be easily dissipated as heat loss. Threshold voltage and leakage current that are inherent in MOS transistors significantly affect the performance of an RF AC to DC converter . A device with bulk connected to its

AC to DC converter design for DC Drive
