“…This design has an efficiency above 30% when the input power is between 0.1 mW and 1.3 mW . Further improvements were done in [9], where a peak efficiency of 60% with a sensitivity of -21 dBm was achieved at 868 M Hz. The efficiency is above 30 % when the input power is between 0.05 mW and 1.5 mW .…”

An active voltage doubler utilizing a single supply op-amp for energy harvesting system is presented. The proposed doubler is used for rectification process to achieve both acceptably high power conversion efficiency (PCE) and large rectified DC voltage. The incorporated op-amp is self-biased, meaning no external supply is needed but rather it uses part of the harvested energy for its biasing. The proposed active doubler achieves maximum power conversion efficiency (PCE) of 61.7% for a 200 Hz sinusoidal input of 0.8 V for a 20 KΩ load resistor. This efficiency is 2 times more when compared with the passive voltage doubler. The rectified DC voltage is almost 2 times more than conventional passive doubler. The relation between PCE and the load resistor is also presented. The proposed active voltage doubler is designed and simulated in LF 0.15 m CMOS process technology using Cadence virtuoso tool.
