摘要：
In this paper a 90 nm power management circuit for vibration based electromagnetic energy harvesters is introduced to generate 1 V from the rectified DC voltage. A mode selector block is designed to detect the output DC voltage level of the rectifier and adjust the mode of the driver block. In order to set the output to the desired level, a regulation system with negative feedback topology is utilized. The circuit is able to operate with input voltages as low as 0.25 V. The simulation results also show that the power conversion efficiency of the regulated system is almost constant for wide range of input voltages.
