Energy management by different complexity level circuits

This work focuses on energy management as one of the main parts of energy harvesting systems. Energy management circuits are classified into three categories depending on their complexity, namely: low - medium - and high complexity level circuits. Thereafter, the idea is to build an energy management solution and to integrate it in two different circuits: medium complexity level circuit and high complexity level circuit. Comparisons based on power consumption demonstrate that the use of microcontroller and high complexity energy management circuits in some types of applications is not convenient and represents a loose of energy.
