The PMICs (Power Management Integrated Circuits) are often required with strict conditions such as highly limited area and power loss as the IoT (Internet of Things) has been developed. Switched- capacitor DC-DC converter is one of the best candidates to meet these demands with its size and efficiency. In this paper, we designed a high efficiency switched-capacitor based charge pump for integrated circuits. The low-ripple is also achieved with smallest output capacitor among the compared works. This charge pump is fabricated with 0.18µm CMOS process and it consumes the active area of 0.068mm2. The 82.2% peak efficiency(ηmax) and 0.15% Output Voltage Ripple (OVR) is achieved in 1V supply.
