This paper presents the performance comparison of three types of full-wave rectifiers for vibration energy harvesting. The first rectifier is consisted of two active diodes and two MOSFETs, and the comparators of the active diodes are powered from the output of the rectifier. The second one is a 2-stage full-wave rectifier. It comprises the basic rectifier consisted of four MOSFETs and an active diode. The comparator is also powered from the output of the rectifier. The third one is an input powered rectifier. It has the same structure as the second rectifier, but the comparator is powered from the input of the rectifier. These rectifiers have been designed using a 0.35um CMOS process and their performances have been compared through simulations. In terms of efficiency, the first rectifier shows the best performance at heavy loads, but the second one is suitable at light loads. When the power consumption during absence of vibration is more important than efficiency, the input-powered rectifier is proper.
