摘　　要：An ultra low voltage rectifier with high power conversion efficiency （PCE） for PE energy harvesting ap- plications is presented in this paper. This is achieved by utilizing the DTMOS which the body terminal is connected to the gate terminal in a diode connected transistor. This implementation facilitates the rectifier with dynamic con- trol over the threshold voltage. Moreover, we use input powered to take the place of output powered to reduce the power loss and thereby increasing the power conversion efficiency. Based on standard SMIC 0.18 μm CMOS tech- nology, the simulation results show that the voltage conversion efficiency and the power conversion efficiency can reach up to 90.5% and 95.5% respectively, when the input voltage equals to 0.2 V @ 100 Hz with load resistance 50 kW. Input voltages with frequencies in the range of 10 Hz-1 kHz can be rectified.An ultra low voltage rectifier with high power conversion efficiency （PCE） for PE energy harvesting ap- plications is presented in this paper.
