Design of an electromagnetic energy harvesting circuit (rf-dc converter) applied to cmos 45nm technology

Abstract

The main topic of this project is a design of an Energy Harvesting circuit using an architecture proposed by a paper (ASL; ZARIFI, 2014) and a doctor thesis (SEIGNEURET, 2011). This architecture is the Dickson Voltage Multiplier, a circuit capable for increasing the output voltage of a circuit which is, in this case, fed with low power energy from the environment. This monograph imposes some constraints and directives to the project and starts by analyzing the equations and curves of the basic circuit of the Dickson Voltage Multiplier architecture. After its analysis and understanding of its basic behavior, the project’s focus changes to create a circuit which satisfy the objectives and constraints set at the beginning. Simulations are performed, like Monte Carlo, and after the results, conclusions about the performance of the circuit are made. The layout of an integrated circuit designed for this circuit is presented on the annex.
