Objective: As the need for energy increases, new technologies should replace the conventional energy resources. Energy harvesting is one of these technologies and finds applications in many areas such as wireless sensor networks, biomedical applications. Findings: This paper presents a low-voltage charge pump which works at input voltage as small as 100 mV and is suitable for wireless energy harvesting applications. With 100 mV input, the proposed charge pump provides an output of 1.05 V. This output voltage is adequate for charging low power devices for biomedical applications and wireless sensor networks. Novelty/Improvement: The proposed charge pump has the voltage conversion ratio (M) greater than 10 and the circuit does not need any start-up voltage mechanisms for the operations. Method/Analysis: The result presented in this work is based on extensive simulation on SPICE and are experimentally validated CNFET model of Stanford University.
