In this study, a digital solar energy harvesting integrated circuit and system synthesis tool is developed with visual basic software. Using this synthesis tool, the design time to market can be significantly reduced. A metering technique is also developed to combine the solar energy harvesting system with an online system. Therefore users can obtain the proposed system's information at any time and from anywhere. Meanwhile, there is no need to buy any additional scope or metre to undertake the measurements. Computer simulations and experimental results demonstrate the accuracy and the superior performance of the proposed technique.
