Abstract

This paper presents a multi-input, multi-output, frequency modulated Dickson charge pump targeting power management unit in energy harvesting applications. Four stages Dickson charge pump is designed and simulated using 65nm CMOS. The design has an input voltage range from 0.4V-0.6V and generates a regulated output voltage of 0.6V, 0.8V and 1V using pulse frequency modulation (PFM). SPICE simulations show that a maximum end-To-end efficiency of 33% at 200 μW at an input of 0.6V is achieved. The proposed charge pump supports a current range from 1uA to 200μA with a maximum operating frequency of 2.4 MHz. The proposed design could help in reducing the complexity of power management unit in energy harvesting applications.
